Horrific Service & Sabotage

I fail to understand why my account has been suspended on 04 December 2020 at 17:00 after taking money from my account. I do not have fibre in my home and I depend on it to make a living. Is the reason related to the fact that I have requested cancellation ? and now you are sabotaging me with worse service than what I have been receiving this entire time. I informed you that I am canceling my service with supersonic due to the horrific level of service received, Yet you are quick to disconnect when it is not yet time to do so. It was agreed in writing that your service will terminate on 31 December 2020 and yet you have taken money from me. This is an injustice to your customers. I demand that I be reconnected immediately as I have paid for this service and should not be experiencing suspensions. Supersonic has taken my money therefore you must give me what is due to me which is your uninterrupted service until termination date. I cannot wait 48hr when you are wrong.
