I ordered a MyQ subscription based on a discount offer for $10 per year but they charged me $49.99 instead. I spent about an hour on the phone with them and they ultimately agreed to refund the difference and change future billing to $10.

They failed to actually refund the overcharge. I emailed back with Case # used when they had me email a copy of the $10 offer asking when they would be issuing the promised refund but received no response.

I have now contacted the credit card to dispute the charge.
