Shocking Customer Support from Mweb

I am an existing ADSL customer. Have upgraded to fibre It has proved impossible to obtain any confirmation as to when upgrade will be completed. The web site has not been updated as to progress. It is impossible to speak to anyone on the phone. I have had 3 calls waiting for close to an hour each time. Eventually spoke to a sales assistant who said she coulnt help but would put me though to the correct person. A further wait for 45 minutes with no response but their infernal messages about leaving a telephone number for them to call back. Have left 3 of these previously no return call todate. What kind of business is this?? Hopefully someone will be able to respond with an update soon.
