Terrible service!

I have been having an issue with MTN for about 9 months now. However in the last 2 months it has just escalated. My account is suspended every other day because they haven't allocated my payments. I've sent through proof of payments and was told to wait 7-14 days. During which my account was suspended twice. It is now past 14 days and my account has been suspended again and when i try to call them my calls get cut. Its absolutely ridiculous.
