Being billed for data not used and roaming calls

Hi MTN<br> <br> I have contacted you call centre numerous times.<br> <br> 1. I have been billed for roaming calls in May, June and July. I asked for this to be investigated, I am on roaming but when i am overseas i turn off my data and i don't answer calls or listen to voicemails. Why then am i being charged? I have queried this and had no response!<br> <br> 2. I asked for my usage limit to be capped. This is because i am being charged for data after my bundle is finished. I dont want this to be the case, if i want data i will buy further data. I dont want MTN to decide they can automatically charge me for data!. I still havent had any answer on this!<br> <br> 3. Furthermore, i dont even use MTN data i use Afrihost mobile data but for some reason i am still being charged for data. I have asked for this to be investigated but again no response.<br> <br> The call centre is useless and when you ask for a manager they say they cant. is this really how you treat your customers. I have been on MTN over 10 years and the first chance i now get i am going to vodacom. <br> <br> I expect someone with authority and customer importance to call me!!! <br> <br> What MTN is doing is pure theft and if it continues i will go to Carte Blanche!!!!!
