Non-existent customer care

I have recently combined a few numbers of staff and taken them over under an MTN business account. To dtae I have not received all invoices and statements. I get a cheeky email telling me to log in and view my bill. When I do, this only gives me 1 of the lines and not all. It isnt even my line, it is one of the staff members. Initially they were only giving me the details of a number not belonging to me and they were adamant that I was wrong, telling me I must get the other company to write to them. How the hell would I know who that is? Seems the hiring criteria is not very high at MTN.

I have since sent 4 requests to MTN customer care. ll have been acknowledged via their automatic response but I have never heard back.

It has left me no choice but to cancel the debit order. Maybe then they will finally contact me. alternatively I will move my business to Vodacom.
