Horrific service

On the 1st September I received an in-contact that R1566.00 was debited from my bank account by MTN, I dropped everything and rushed to the Centurion mall branch to find out as to what is happening because I use prepaid sim card. I was told that there were 3 contracts opened under my name, I was then advised to go get an affidavit from the Police and also to bring my certified copy of my ID. On Monday morning 3rd September I submitted the docs to Tsakane Makhubela who promised to keep me updated, NEVER HAPPENED. on 30th September same thing happened again R2665. was debited by MTN, I then went back to Centurion mall branch, I was told they are still investigating?? until today nothing has happened! it is easy for MTN to say you can go reverse a debit order!!! DO YOU HAVE ANY IDEA AS TO WHAT REVERSING A DEBIT ORDER DOES ON ONE'S CREDIT RECORD?????

This is snot acceptable at all! I wonder how does MTN allow this to happen from the first place??
