Zoom Fibre Bad Customer Service

I have been trying to get into contact with Zoom Fibre for sometime now by email, calls and whattsapp but there's been no response so my question is if you they don't respond to potential clients how will they service be like as a client. The calls don't go through, the email they logged a ticket but no response for days and the whattsapp they ask for the address without asking what is the query so I gave my address then they go quiet and before I contacted them I checked my own coverage on the coverage check. I sent another WhatsApp asking for feedback they ask for my address again they only ask for the address nothing else and keep quiet again and I tried again they asked for the address again. This is really not a good way to assist potential clients because right now I'm having serious doubts about their services.
