Contract transfer from nashua mobile To mtn

Hi<br> <br> I have two issues that i need urgent attention response on. <br> <br> mtn took over my account from nashua mobile and since then my bill went up by over a R1000 a month. After numerous attempt to have this rectified we found the problem. I was on a anytime 500 contract with a 250mb data bundle now since mtn took it over they changed the bundle to 100mb only. Therefore my data runs out quicker and start depleting my talk time and in no time im paying out of bundle rates for calls and Data. We have been in contact with the call center for 3 or 4 months to sort this out and to date nothing has been done. We are talking R4000 in over charges here. We need someone to sort this out and not keep blaming nashua mobile and take responsibly for this. <br> <br>
