Cannot cancel contract!

I requested that my contract be cancelled and received a reference number and an expected timeline of 48 hours<br> 3 days later I received an email with a different reference number asking some questions as to why and re-requesting all my information. I tried to call the retentions department, but didn't have a number. I called the call centre (808) and got various responses - 1 no such number - called back - got a call center number which was a message saying the call centre is no longer active - called back - got 2 fax numbers - called back and was told that the retentions department cannot receive calls. This is just 1 example of why I am leaving MTN!
