Upgrade billing

For the past 4 months I have been having issues with my upgrade and the billing of this upgrade. I have lost more than R4000

4 Months ago I was notified that I am due for an upgrade soon and that I must visit a MTN store.

I went into the store and did the upgrade in time. The info was done and uploaded in time. I was told there is an issue with the new system syncing with the old system and that it will eventually be fixed.

The next day I again went in to check if all was okay and was assured it would get done. I even had to pay some money for the upgrade to be effective.

My contract is R499 and R149, so I should pay around R650 per month for my MTN contracts.

I make sure there is enough money in my account when my MTN bill comes in.

However I was not planning on paying more than I should.

I have paid more than double the amount I should be paying in the last 4 months because of these upgrade issues.

System down? System just hanging? Upgrade pending?

I have visited the Soneike Kuilsriver MTN store 14 times in the last few months and still they can't give me any clear answers to why I have to spend so much money on this account.

It has caused massive financial stress on our home and relationship.

My bill should be R650 per month. I have been paying a lot more than I should be.

How can I get my money back?

Please check all this info and assist.
