MWEB move of fiber line to new premises.

I have moved home and I've been struggling since 29 June to have my fiber reconnected. Everything is already installed & Openserve is supposed to connect, but I am still without internet. Mweb sporadically comes back to me via email. Openserve tried calling me once & reported back to MWEB that I'm unreachable. What do I have to do to get service. It's really not complicated. Your service level leaves MUCH to be desired.
