****med by MTN

I took a month to month router contract onlline on the 26th May and i paid R297 upfront fee. The router was delivered on the 31st and i was told it will be ready to use on the 2nd. I tried to use the router, since it was sent it has never worked. I now take it to MTN store in centurion and they advise that its an internet issue on 05th. My surprise, when i check my account they debited again R249, remember i paid upfront prorata. And all this for something that has never worked even no it is not working. I want my money back as i went back to the MTN store in Centurion and they tell me that they cannnot cancel for me as it is online and that the sim is rica. They do not know why it is not working. I want my money back. This is a **** i cannot pay for something and not use it. Can i please get my money back ASAP.
