Dissatisfied n disappointed customer

On 12 May 18 i purchased R40 uncapped data n i activated it but it was not showing in my account. I called mtn customer care n was told dat this option is no longer available for contract user's so dey will do a reverse transaction n recredit my acc until date nothing has happened. Everytime i phone n complain mtn sends me tickets with reference no's n den sms me stating ur query has been resolved n if still occurs i must call mtn within 48hrs but when i check my acc it still shows R00.00 n when i call mtn again den again they say dey gonna sort it out but to no avail till date n its so frustrating coz when we owe dem money on time dey debit our acc but when dey have to credit us den it becomes a big issue n no one wants to help. I even requested for to speak to a supervisor n i was told she is busy on another call so i requested dem to ask her to call me when she is done n till now no supervisor has returned my call.
