Terrible customer service

We have moved house this past weekend and I advised Home Connect in the beginning of July and we're still struggling to get our wifi connected. Ive made numerous calls and still have no resolution. Also asked for an immediate line release as the tenants have moved into our old house and cant have their fibre installed until such time that the line is released. The customer service is absolutely shocking. I've spent almost 18 min on a call today and the call got cut and no one will even phone back. Only feedback received is that they will check with Operations, but no feedback is given. Really annoyed and feel like cancelling the service.
