Offer to retain turns into a nightmare

I received numerous calls to renew my contracts with MTN. when at last I decided to give them another chance and renew, I was offered a retention discount . what a nice gesture, if only it could be done. this was credited to my account and removed again. I have been calling for more than a month to sort this out. in the meantime my service was suspended and then reinstated again and now once again I am being threatened. after giving them a month to sort themselves out and hoping they will at least do their jobs without me having to beg to do this. this was the worst decision I made to renew 2 more of my contracts with MTN. I currently have 5 contracts with them and cant wait to get out of it. I have given up all hope in ever being satisfied with this service provider. I have spent countless hours on the phone holding on for you and listening to your key man problem where no-one can help except the one that sent the request and they are not at work. how pathetic for a company as big as you to still have such outdated processes. <br> <br> I want a breakdown of all the contracts I have and the costs to buy out of these contracts earlier. Enough is enough.
