Axxess won't terminate my subscription, 3 months since I've given notice

I switched my 50/25mbps package from another ISP to Axxess in Oct 2024, meaning, I came with all the infrastructure. Same month and in November, I noticed that I was getting very little for my money; as low as 10/7mbps or 3/0.5 mbps while I was alone in the house and on the network. So, I raised the concern with them. On both occasions they'd blame it on Openserve. My neighbourhood has always been running on Openserve infrastructure but I've never had the problems I have with my connectivity before. So I tried canceling in January, and they told me about the fee for installing their infrastructure. Cancellation fee for what, when I was still using the Router from my old service provider, and I've been complaining to you that I'm not getting the service I pay for! Ok, well, cancellation must happen. By January, my account was debited, and by the end of February 2025, my account was debited again. What is going on Axxess!!!
