Nashua Mobile to MTN account

I used to be a Nashua Mobile client. MTN has taken over the Nashua Moblile MTN contracts.<br> <br> I used to pay R800 odd for my account per month. since the change to MTN I am being overcharged monthly.<br> after a week or two into every new MTN disconnected my account. after payments was made, my account was activated only to be de-activated once again a few days after.<br> <br> then all of a sudden my account is in arrears for R9000.<br> <br> today I was called, now its R13,000. an this with my account disconnected 3-4 months ago. how Ridiculous.<br> <br> I have sent numerous emails to customer complaints asking someone to investigate...no body bothered.<br>
