Supersonic ******* debit orders

This has to be the worst company to deal with. I am speechless! I signed up for an internet service which was meant to be 50mb line. Free to use router. R999 activation fee which included, according to the call centre sales person, courier to get router delivered and collected on termination of contract. Line did not deliver what was promised so I cancelled after 6 months on 1 Oct 2023..Paid my last installment of R999.00. I was advised that the router would be collected. After lots of mails back and forth as my address was incorrect on their records and absolutely no acknowledgement of this by Supersonic I was told I must pay for the router or return therof. I informed them I had cancelled the contract and they could collect the router. They collected the router and at the same time *******ly debited my account for R5019 to pay for the router that is no longer in my possession.. I mailed again and had absolutely no response. I had my bank reverse the debit order of R5019. I was then invoiced R250 for collection of the router. Once again another Debit order for R5019 plus R250 was *******ly deducted from my account on 3 Jan 2024. This is mindblowing that any company has the right to do this. It's pure theft. Be very careful of Supersonic. I will never ever recommend them to anyone and judging by all the bad reviews they seem to do this all the time. Customer service is non existent.
