Mtn sucks

I called on the 10th to load once off data . That data was loaded on the wrong number. I then called back and asked they delete it and out it on my right number which ends with 4750 . I was assured the incorrect bundle was deleted on the 060 number when I checked my balance It was still ther. I then called again and spoke to Palesa who advised me that the bundle wasnt deleted but I should call on the 18th and they will add that bundle aa credit before my bill generated. I called on the 18th and Mosa said she did it. It came as no surprise when my bill was generated they 2gig was still charged . Phoned on Friday AGAIN TO sort this mess and spoke to Mpho who promised to sort it out and call me back. Its Sunday and my bill is still wrong and he didn't call back. What kind of service is this when I have been a loyal customer to u guys for 10 years ??? If this is not sorted by the time my debit order runs I'm going to reverse this debut order and then we will fight head to head. I'm sick and tired of calling and being promised empty promises. Your staff must be delt with and take accountability. You guys know nothing about customer service and experience. You just milk our money for nothing .
