Growing Grey hair waiting for a sim swap

I was contacted by The Foschini Group (TFG) marketing their airtime top up contracts. I took a contract for my father to be topped up, they did not inform me that the contract is automatically renewed after 12months, they also failed to inform me that my faher's sim can will automatically be transfered to my name even after the contract expired or is cancelled. His phone was ****** and when he tried to do a sim swap, he was denied because his number is now registered in my name. When i went to do it for him, I was told it will take 24-48 hours. Its now over a week and sim swap has not been done, I have called the customer care number, only to hold for hours on the answering machine.. My father is losing his clients and a lot of business as he no longer has access to his own phone number. What does a person have to do to get good service with this company? this is really not fair.
