dissapointing response time from staff of mtn

I was advised to pay my account cash since my last problem with mtn when some on did a ***** transaction on my name, so since then I have been paying my account cash. The last 2months unfortunately the reference I was paying into was wrong with one digit (A***/A***) hence I called in to rectify the problem after I sent Ronelle an email to ask her if she could assist but I got no feedback from her so after holding for 1hr I was told by an advisor to send it to [Email Removed] of which I got no response and then I called again and spoke to Paul Mthembu who said I must send it to him of which I did and also there once again I got only one response that he received the docs but then after me asking him the next day if it was sorted, no response and then the next day I sent another email only then he advised it will be sorted and this as know the 1st of June since the 26th this query is not sorted, I then called in today and which is the 9th and was advised it is not yet sorted and it is know the billing divisions fault. Seriously, am told it would take 2 to 5 working days after so long already. Might as well cancel this contract and never again deal with Mtn. ridiculous
