MTN please fix my billing and refund me!

On the 29 September 2017 I upgraded to a data package. The adverti*****t said pay for 20 gb of data, and receive 40gb. So 20 gb day data and 20gb night data. The price was advertised as R299.00 incl vat. The first month I was billed correctly: 19 October 2017 MTN CHOICE 10GB SUBS FEE R455.26 MONTHLY SERVICE FEE DISCOUNT - R192.98 TOTAL EX VAT R 262.28 VAT R36.72 TOTAL INCL VAT R299.00 Then came the problems, the first month the data I was issued was incorrect, and after going to the MTN store I was told they had issues with the contract, and that it would be fixed. After about a month the actual data I was being issued was corrected, but then came the billing nightmare.

Firstly my contract should have been R 299.00 and not R729.00 and I was being billed for a recurring 5GB of data which I never asked for and never received.

Now my bill is less, but I have not been refunded for all the past incorrect billing, and the billing is still incorrect. I don't want to pay less, I just want to pay what I owe every month, at the correct amount which is R 299.00 plus a bit more for the vat adjustment in April.

I have logged various calls to no avail.

Can someone just sort out my billing query please.
