Working in the high revenue customer care team for a telecommunication company, an extremely angry client called in to be transferred to the team who do the cancellations as he wanted to cancel all his accounts with us. I advised the customer that I'm sorry to hear that and if I could ask why the change of heart? The customer was so frustrated and adamant that he did not want to be helped in any way and just did not want to deal with us anymore, I did not want to put the client on hold to frustrate him even more, so I just asked for a moment explaining that I need to quickly go through the last note on his account to be able to explain briefly to the cancellations team prior to transfer. I read the note as quick as I could to avoid a long delay and this gave the client a moment to calm down a bit as well at the same time. The client had called in about a billing issue that was not dealt with and it was ongoing, and unfortunately the last couple of representatives did not show much care (however I did not voice this to client instead I worded it differently) I advised the client that I see you have had billing issues the last couple of months and it seems that it is still unresolved, am I right? In which he responded yes and started to explain with frustration that he has to go through this every time. I was empathetic with the client and asked if he would give me the chance to correct the issue as I may have the ability to fix this once in for all, even if it means to follow it up as often as required, that I will personally take over the matter and if unable to resolve, I would credit him for cancellation from the day of request so that there are no charges here onwards if unresolved only. The client calmed and accepted. This was an agreement I made with the client knowing that it would have been a greater loss for our company to lose the client and I was confident knowing that there is a high chance of correcting the issue. I advised that I would call him back as soon as I have more update. I contacted the departments required to assist me in correcting the issue. Due to it being a system error it took a couple days to fix, however I made 2 calls to the client, first call to explain the likelihood of correcting the matter and approximately how long it may take, then the second call a couple days later following up with a resolution. The client was very grateful and regained faith in the company expressing his appreciation and even made the time and effort of giving positive feedback about what I have done for him. I was extremely happy to be able to resolve this and save the client. It was a win/win situation for the both of us!
