MWEB call centre never available

I have tried to call MWEB 5 times over the last 10 days to discuss my fibre application but never managed to speak to anymore. I am put on hold and after waiting patiently for 10 minutes, I'd have to hang up.

I have emailed them several times as well, same automatic feedback email "Thank you for sending us the information we requested. We will now progress with your MWEB Fibre order. No need to call us, should we need anything else, we will contact you. Yours in connectivity, MWEB"

My application only needs to be activated as there is already a line in place and it has been released by a previous ISP.
