Mtn Worst cellular service provider

14 months ago I asked MTN to move 5 numbers to my wife's business account with new banking details. Since the 1 number was detached from the 5 now receiving two accounts and the numbers have not yet moved to my wife's business. I have been into my local MTN store in Ballito more than 15 times and still not rectified. To top it off because I have canceled the debit orders on my account we have to pay manually. In doing so they have not allocated one of my payments and I have given proof of the payment yet my numbers have been suspended. This is a disaster and MTN just seem disinterested in assisting. I want to cancel all 5 numbers immediately should this not be rectified within 48 hours
