Fault not repaired and no phone call as promised

We have had ZERO telephone (and consequently ADSL) connectivity for over three weeks. Prior to that we had poor connectivity for two months but at least we had some service.<br> <br> I've phoned almost daily for weeks, requesting that the technician give me feedback on the nature of the problem, and an estimated repair date, and not once have I been called, despite being promised that the technician \should get in touch today or tomorrow"every time.
