Bunch of ****my bullies!!!!!!

I just wasted a star! Fibre line active 17 August, charges start, router delivered 24th August, charges continue. 25 August unable to get service to work, eventually cal, out an IT tech, more charges. Six hours of calling support only for the calls to be dropped every single time, more charges. Cancel due to lack of service, won't release line if I don't pay a penalty, so basically hijacked my line to bully me into paying for zero service, no support, not 1 kilobyte used. Now retention says they will send a support technician to fix the problem. I DON'T want Mweb anywhere near me, have cancelled my other fibre line as well. They are mistaken if they believe they will bully me into paying for absolutely nothing!!!!!
