One of the toughest jobs any one can get is to convince, help, pacify, persuade a complete stranger, who is very valuable to your employer. It's easy to yell at someone if you do not get the required services, but what the person at other end goes through is both embarrassing as well as hilarious.
Only a person who has done a job on will understand this.
1. You become an expert in taking any $hit given to you:

One rigorous training given to such employees is to be patient even out of the limits. Dissatisfaction is a very dangerous thing that can happen to anyone, and when you get a client who is super disappointed, all hell breaks loose. One art that you learn with such an experience is to have an invisible hollow passage created virtually by your imagination which passes from the ear which has the receiver to the other one.
2. The Awesome Mute Button:
Even after taking all you can, that too out of limits, the "MUTE" button comes to the rescue. It's simple to use, just a button to be pressed, give all the bad words you know to the person on the other end, unmute the call, say words of empathy. Do make sure that you've pressed the mute button. I remember an incident where I thought I have done the honors, told my colleague, "ISKA SABUN TO BAUT SLOW HAI." The embarrassed customer then voluntarily kept the call. I was lucky enough to not use any golden words that day.
3. The Words of Empathy:
You learn the ways of retaining your customers. Putting yourself into the customers shoes is considered as the most important thing. And with so many customers handled, you get a hang of the best ones. One dissatisfied customer and a series of words and sentences you start rattering, no matter what is the problem. No matter if you're talking to the customer for the first time, he feels like he is the king.
4. Sorry, don't work:
These kind of customers are tough to handle. No matter how much you convince them with the helplessness of the technical issues, you are bound to just listen to them without any arguments. According to them you're not sorry and you do not understand what they're going through. Give up!
5. Hungry for Customer Feedback:
After going through a lot of depressing calls, comes an angel customer. These type of customers are stuck for a long time at a particular thing. That thing might be the silliest thing you know, but for him it is something totally new. One call to you and the issue is fixed within seconds. You cannot miss this chance to get a feedback for the one-line support which has increased his satisfaction levels to Himalayan heights.
6. Mr. Know-it-all:
These kind of people want to know everything about the product/service on the same day itself. They turn out to be one of the satisfied customers. These calls mostly last from 30 minutes to 3-4 hours. The best part is that you are allowed to take water, tea and loo breaks in between such calls. Consider yourself to be in a dangerous situation as you're going to be a target for any problems faced by this customer in the future. All the best! (Y)
7. Your name is just not the same:
This is when you start helping a customer by introducing yourself and you realize you need to introduce your name in a very funny accent, if not to get the exact name pronounced but atleast something which is close to your name. And then comes a time when you give up correcting your name. I remember one client calling me "Jacinta"and another one who started to talk to me in Punjabi after hearing my name. Only way to get rid of this is to award yourself a pseudo name !
8. Not interested
This one is specially for the guys who work in sales. It is a tedious task to get leads for the employer. Something even more difficult is to talk to direct clients. Corporate sales are much easier ones. than the kinds in which you need to sell credit cards. This is the most depressing job one gets. You have certain targets to be met each day, and almost every call you make becomes a zero call. And that one angel who listens to what you have to say, makes your day but still does not turn out to be a lead. At times, even listening to someone makes their day. Suggestions for the reader is to end such calls politely, or to get yourself into on such jobs for atleast a month and know how it feels to be a tele-caller!
