MTN makes a mistake, I pay for it!

I was so excited to upgrade my router + data contract with MTN for another 24 months, but that quickly turned into a nightmare real fast.

After my router was delivered, I quickly set it up and I was shocked to see that I was upgraded to an incorrect package (Much less data but same price). I called them, they gave me the run around as I've grown to expect from them: 1. I was told they can't correct it and that I'd have to cancel. 2. I called to cancel, but was told they can't do it over the phone because of the nature of my contract (hybrid) and that I had to find an MTN Direct Store in my area and return the router. Which I did. 3. I called them back with the reference number to show I have returned their router, and was told they have sent the cancelation through. All this was done in within the 10 day period MTN assured me I could cancel my plan with them if I'm not happy.

It has been two months and I am still paying for a contract package I didn't ask for. Mind you, I don't have a router now.

Every time I call, they keep telling me the same BS, "You contract cancellation has been sent through" and yet nothing is evident to me.
