Questionable service

I have had no issue with Supersonic until now and even promoted your services to friends and family. I had advised Supersonic that I was moving to a new premise and was told to cancel my contract and take a new one, which I did. I went one further and upgrade with you, too my sorrow! After cancelling the contact I received a Claw back invoice on the 15/03/2021 of 2276.94. No breakdown of fees just the invoice to pay, I have requested a breakdown on numerous occasions to no avail. My contract is month to month however I am now told I have a 24 month contract. I will give you the benefit of the doubt, even with a 24 month contract my service should have been transferred to the new premises, I should not have been told to cancel and take out a new contract. And now threats, “my service will be terminated in 3days”, that is unacceptable!! Expecting me to just pay because you say so is madness, what am paying for when I was instructed to cancel and take out a new contract. Representatives of Supersonic are now holding me to ransom for a service I actually have and do pay for because I need the service to work from home to earn an income for my family, that not good business practice. I find your actions deplorable and *********, how have I been treated fairly
