MTN Doesn't Care

I upgraded my existing contract online from a cellphone contract to a data contract. I did not realize that the data contract would bar my contract number from making calls and using the data on my phone. When I called them they said the only way they could help me was if I canceled the data contract. To cancel the contract was a mission on its own where I was sent from pillar to post until I was directed to an independent company for the cancelation.

I called the company to cancel the contract on the 16th of April, till today the contract has not been canceled even after numerous follow-up calls and each time being given empty promises. I am still stuck with the router trying not to use their data to avoid extra charges but the sad part is I receive the previous contact's data and airtime but I cannot use any of it because my sim card is no more usable on my phone. I cannot afford to loose this number because I use it for my personal stuff.

I get the feeling that even though I have been a loyal customer to MTN for many years, they don't care about me or my personal life.
