Complaint Advice to BT

My advice when complaining is:

a) Contact BT using email rather than over the phone, as this means you have a record of correspondence and also that you don't have to wait on hold.

b) Explain yourself clearly and concisely and be specific about the action you would like BT to take. Always be polite.

c) If your complaint has not been dealt with (and it is reasonable) then begin following BT's complaint escalation guide

Do not keep using their basic complaints service.
