I WANT MY REFUND

I am not happy with what they did to me, I logged into their website on the 25th of September 2024 to cancel my subscription and the pop up message said they will send one of their driver to come and collect the router on the 15th October 2024. On the 2nd of October I received a call from their sales person regarding my cancelation and she asked why am I canceling, I told her I have suffered 3 days because of the network so I want out. She then insisted on sending the technician to come and check our connections. On the 15th October they debited , I called them asking for clarity on why they debited while I canceled my subscription, and I was told that the sales person that called me on the 2nd October that sent the technician removed my cancelation on their system, so now I called several times until they agreed to come and collect their router on Friday 25th October 2024. So my problem is that they don't want to refund me.
