Account overbilled since Nashua take over!

I have now gone out of my way to call MTN to get this sorted. <br> My billing is still wrong! MTN took over my Nashua contract and the contract I signed has a limit of R489 not a cent more. MTN took it upon themselves to add a limit of R750 on top of that, which in December as soon as i got this notice I called MTN to have this limit taken away and the consultant said they would sort it out. I have now been bill R800 odd this month!!! I have all communication via email with the consultants. There is no money owed to MTN. I signed for ONLY R489 a month with Nashua. It is not my problem they sold that is the contract I signed with them. <br> <br> I have emailed MTN multiple times and I have complained on hellopeter before which they completely ignored my actual complaint and commented about something that is not even relevant to what I am complaining about. <br> <br> I have put a stop order on this current debit. Call me at 12 this afternoon and if I do not answer send email me. I have gone out my way to sort this and MTN could not be bothered.
