Totally ***********

When MTN changed their billing system many months back I started receiving my various accounts on the incorrect email address, my personal accounts being sent to my business email address. Just as well the postal service has collapsed because if they posted them to the addresses printed on the documents they would never have got anywhere, please remember that all these details were 100% correct prior to the change of the billing system. I tried to get this corrected last year got as far as getting the postal addresses corrected but nothing else so eventually gave up. I started to try again in July this year and always get the message that this has been corrected and my query is now closed and I still receive my personal accounts on my business email, how hard can this be to change or is it a case of pure incompetence.
