Overcharge on data contract

Hi MTN

I entered into a SIM only data contract as advertised by you for R89 a month for 4GB of data. I have been charged R352 every month instead of the R89 as advertised and as requested when I went into the store to enter into the contract.

I have called in to enquire and rectify only to be told that I need to go into the store to resolve. I have been in to the store twice (at the end of each month when I get my bill as I now have the contract for 2 months) and each time they appear to fix something on the system and say the problem has been resolved but I continue to be billed R352 for an R89 contract.

Somewhere your systems have a glitch. Please resolve ASAP. Fellow MTN data users, please check your statements as you may be overcharged too.
