Shocking Service

I Truly disappointing it the service received by MTN. I have been a loyal client of MTN for years now, and have never missed one payment. This month however, my account was suspended....i didn't realize that the debit order didn't go off. After trying to get hold of the customer service on 135 on numerous occasion just to confirm that the payment was not made. It kept on notifying my that they are experiencing network issues. I then tried logging into my application and could not access it because it required an OTP that would be sent to me via sms (cant receive sms's because my account is suspended) this would also not work. So my question is how do i confirm the correct bank account details if none of MTN services is available? I also received two separate mails with MTN banking details(that was different) and how do I know if this information is valid and not **********??? To add insult to injury I received a mail where it stated "MTN sent you a number of SMS's About paying your account" and threatening me that I have 10 days to pay the outstanding moneys (with yet again other banking details)..... Just to confirm I have yet to receive one notification from MTN via SMS notifying me that i missed one payment. (Believe me i want to pay...but because of the shocking service and the fact that no one gets back to me ....how am i supposed to pay in the money). Then after numerous attempts from my side to get hold of a MTN consultant....I receive another mail today to notify me that MTN will be cancelling my contract and it states that "you haven't responded to MTN's notice) and that i have to pay the early cancellation charges! So my question is ....is this how MTN treats their long standing clients???? Shocked and so disappointed ........ All i want is for someone to get hold of me to confirm the banking details.......
