Mweb fibre

I have been a satisfied Mweb customer for at least 12 years now, using an ADSL connection. I signed up for fibre recenlty. The fibre installation was duly done satisfactorily by SADV, the router was delivered and I am now trying to get the thing activated. Mweb are impossible to get hold of. I phone the technical help and get a very pleasant and competent agent who informs me that the account needs to be activated. He attempts to connect me to activation and the cal disconnects. I try to phone sales for help, the call does not get answered. this has happened twice now. One cannot email anyone to register a complaint, the phone does not answer, when you do get connected the call drops. Mweb needs to jack up their customer service or they are going to lose a lot of business.
