MTN Wrong Package Issued but no solution provided, overcharges carries on.

Good day:

I have signed a contract with MTN for a package of R149.00 Per month 10GB Day, 10 GB night Data Sim, in September 2019.

And i only discovered 1 - 2 months later, they charging R200.01 per month. After querying it, only found out that they gave me a wrong package.

I requested for itto be fixed in November, solutions and refunds were promised to be given but only for the period after reported this issue, not the september/October month. and working days of 5-7 days passed, averagely 2-3 calls a month was made then i was finding out the issue was not resolved.

And this month, they finally told me wrong package is issued, i will have to do a migration at my own cost?? Why should i suffer a cost fee, with MTN's mistake and yet still no one tries to attend this issue?

This contract was done at Nicol Way branch. I have contact them numerous times, lastly, i was requesting for the contract that i signed for, and they fail to even respond and provide that to me.

If this can not to be resolved, i will have to request a cancellation since this was never the contract we agreed to and i dont think my contract will be liable, since its completely different package now.

Urgent solution and responded needed.
