uncapping of account & unkept promises of response

My husband's account 'suddenly' became uncapped after a number of months without any written warning as well as the device still indicating that data was available. The history of the account shows that it never went over the capped amount... it has been imp**** that we are lying, the proof that the account was capped is in the history of the account, which they will not acknowledge by MTN. We especially went to Canal walk to fetch my tablet and have his account capped as the consultant who dealt with us and knew that we would never take an uncapped package had forgotten to inform him that it was not capped so we SPECIFICALLY HAD IT CAPPED. <br> We keep getting promised to have this sudden uncapped issue and bill dealt with, but it has been going on since the beginning of the month when they took extra money out of my husbands account and want to charge us next month for their mistake.<br> Days have passed since his last complaint on Hellopeter and no one has bothered to contact him or sort this out. He has been with MTN for 10 years and we find this treatment and lack of customer service disgusting. it is disrespectful to ignore people and just take their money & provide empty promises<br>
