BT is a member of the Communications Ombudsman, not CISAS. Ask for a deadlock letter if BT cannot resolve the issue so you do not have to wait the full 8 weeks.
Complain to BT first and ask for a written final response. If they reject you or the deadline passes, you can take it to the Communications Ombudsman for free, and their decision is binding on the company.
