No technical support

I transferred my existing line to Access on the 6th Jan 21, since the transfer I have not had one day of internet. I have called everyday been on the phone on average 3 hours while they reconfigure the router, flush, manually link the Mac and IP address. The technical support is abosulutely useless because they keep reading the same trouble shooting guide, I've asked for this to be escalated to management and was told I would receive a phone. Still nothing. The technical team and service are absolutely useless and I'm now 3 days without internet. No one can tell me why there is no internet
