Overcharged

During the months of February 2015 and March 2015 I was not credited with the Recurring SMS100 Disc. I have complained on numerous occasions and to date this has still not been rectified. My account number is A***. Please advise when can I expect this to be rectified. MTN reference numbers are MTN REQ:***, Billing [#***], Billing [#***], Billing [#***] and Billing [#***].<br> <br> According to a previous responses by Bongi and Mantoa, this was going to be corrected and credited to my next invoice. Well I have received my next invoice and once again there is still no resolution as the amounts have not been credited to my account.<br> <br> I have again received my statement and nothing has been corrected. It is easy to expect rain in a desert than to expect MTN to correct their errors. All you ever get is empty promises, but make no mistake they will never forget to debit your account at the end of the month.
