Home address not in the list. It has been 1 week already and they still didn't update it. What to do?

Yeah, I contacted them a lot. They have no phone number to call and their customer service has no contact with the IT department, so no way to know how long it will take more. I am in a big hurry for wifi and another company fixed that problem in 1 minute through their live chat (instantly)... So I decided to cancel my fizz plan as I cannot afford to wait longer and will go with the other company.

Was expecting fizz to have it within 3 days and book a technician asap. Now there's too many 'if' factors. Slightly disappointed, maybe will use fizz in the future, who knows!
