Incorrect migration

I was migrated to a lower data package from an uncapped data package to a 5gig data package. Logged an enquiry with the mtn galleria store on the 9th July. Visited the store the 12th July for an update on my enquiry and was told by the sales consultant that my enquiry was emailed to the head office and I asked him for head office Contact details and was told that I cannot contact them, what bulks hit. I am the contract holder and I pay the bills. I called the mtn call centre in 808 on three different occasions there after obtained reference numbers a d was told that they have escalated my enquiry to the revelation department. I am still waiting. I receive calls from the mtn galleria store almost everyday advising me that my enquiry has still not attended to. In the interim I need to recharge once the 5gig data is used. How long does it take to resolve a simple system error, if that is what it is. Absolutely disappoint in the service provider. Incompeten*********** people at call centre and head office level.
