I took an online home wifi router contract with a premium of R399 monthly

I took an online home wifi router contract with a premium of R399 monthly. My debit order was unpaid on the agreed date which was 07/09/2025 and this resulted in data being switched off. I made a payment on the 20/09/2025. On the 07/10/2025 they debited R4600 which didn't go through, I called to enquire why such a huge amount I was told its clawback which the company put on a client's profile when they dont get funds and I was given a link to make a payment which I did. A day after on the 10/10/2025 they successfully debited R798 and when I called for a refund I was told the company does not refund instead it will be an advanced payment for November and December and will pay in January the 15th. In November they switched off again. I called and it was switched on. In December the same problem incurred but this time I was taken from one department to another without any success. I am cancelling their contract to have piece of mind.
