Cancellation of contract

Yesterday I was on hold for over an hour and was cut off as I was trying to cancel my phone contract. Today I tried to call again, was on hold for an hour and was cut off. I tried to call again, and the same happened. I NEED TO CANCEL MY PHONE CONTRACT BECAUSE I CAN NOT AFFORD IT ANYMORE DUE TO FINANCIAL PROBLEMS!!! I only have 4 months to go and have been paying my contract for 20 months now and have been a loyal customer for over 7 years now.

This is the worst service I have ever received from anyone!!! I was thinking about going on pre-paid with MTN but I think I will just move to a new network instead.
