Not off to a good start

Placed an order last week with my ISP as I was moving house, they then provided Vuma with the details and I was contacted by Britelink on Monday to send a photo of existing installation so they can activate it. They need to send a technician to get the ONT details on site but I am now waiting with zero indication of when they will send a technician. Their customer support was friendly enough when I emailed but they have no answers as its sitting with their maintenance department, so it could be days, weeks, who knows!! I would appreciate a clear deadline today so that I know if I should cancel and look at mobile option instead.
