MTN SA are ********** and *******

MTN SA are theives, *****ing money from customers through ********** activity. They deliver the incorrect device 1stly, then it's a mission to get them to rectify that of which they state they cannot send the correct device but only collect the wrong 1 delivered. Then they continuously debit my account till date despite taking back their device and advising me that I will be refunded in full as it was their mistake. I had to turn to social media to get a very tiny response promising to have this resolved asap but to no avail. They just keep *****ing my money.
