MTN has *****

A week ago after 21:00 at night I started receiving SMSs from MTN saying that my order was approved. I had not ordered anything. By 21:10 a sim swop was done and my Bank account was accessed. I called 135 hung on for more than 10 minutes. The Agent was very helpful. The new line was suspended but it didn't stop there. Someone on the MTN system was busy changing things on my account. My primary number was replaced as well as my credit limit and the poor agent couldn't do a thing. Someone was using a supervisor log-in to **********ly change things on my account. A ***** case was opened but I was inconvenienced to have to go to the police station and make a affidavit saying I did not request any of the changes. even though everything happened after hours. I am still waiting for them to get back to me and now I have been charges R200 excl. to my bill for the new number. To make things worse today at 8:42 some one again changed my MTN credit limit. A supervisor was to call me. I am still waiting. We have no power against this *****. MTN cannot keep our accounts safe. I am also going to get legal representation and take this further. They have got ********** working for them steeling from the customers and they just ignore this. I will be posting messages on all social media platforms. this is ridiculous!!!!
