MTN BILLINGS SUCKS / DATA A RIP-OFF

Not sure what is happening the last few months ? I've been an MTN client for more than 15 years. Account has always been paid. I pay via EFT before the 1st of every single month. Last month all my line was suspended on the 1st because payment didnt show. When I called I was told I must pay before the 25th. This is not what my contract said and never said before. I had trouble getting my lines on for three days. Now again on the 18th I get messages to pay Profiles BA*** and BA***as i will not be able to make calls etc. I dont even know if these profile numbers belong to me as my account no's difffer. My cell no's are ***, *** and ***. MTN has become a **** network to be with and I really want to cancel my contracts and be with a service provider that appreciate their consumers. If the accounts changed, I was not informed in writing. And if MTN did merge with another company the current contracts should not be affected by this. I do not get paid before the 31st of the month !!!!!!! And then our data dissapear like crazy. It is a *******.
