MWEB call centre and VOIP frustrations

MWEB used to have a good call centre, quick to respond. Now it seems that they, like so many others, blame Corona for shoddy service. I have been trying to get some technical advice on a VOIP line that I have just taken up with them but trying to get hold of someone is near impossible and simply runs up my landline bill and their 'Help' bot is just frustrating to say the least and not helpful at all. I want one of their technical agents to contact me now as I am getting fed up. I have my business and personal fibre lines with MWEB.
