Mweb, terrible customer service

I have an account with mweb and moved property and need the fibre set up in the new premises, I have been calling since beginning of Feb with no joy, you phone and you stay on the line for ever no one phones you back when promised, I have now moved into the new property and was promised a call to set up but nothing, I have tried to call three times with no luck, the service is shockingly bad, I need to now cancel as the service is so poor.
