FREDD/TT CONNECT - THE WORLD'S WORST SERVICE PROVIDER!

I have been utilising TT Connect/Fredd for a 100Mbps Fibre Line since Febraury 2018. and had regular downtime. Everytime the line is down it takes them 2 to 10 days to attend to the problem. I also never got near the promised speed of this line, it mostly ran at 20% capacity! For 2½ years they took money off my account by debit order and never issued me with an invoice or receipt! Thus, I dont even know my account number with them! The worst was still to come. On 23 July 2020 I decided I had enough and emailed them to cancel the month-to-month contract I have with them. They refused to cancel the contract unless I complete their cancellation form and give them 30 Days notice. After repeated requests, they eventually sent me the form on 28 July 2020. On the form they want my account number. Again I asked for my invoices and account number and 6 hours later no one bothered to respond to me. It is just the World's worst service you can ever imagine. It is not that they just don't care, they deliberately make their customers' lives difficult.
