Bad service and consultants dnt know what they are doing

I have used fibre n internet services before I have never came across such bad service in my life I app**** for fibre and on the 13th of November I was told that I'm approved and I should be activated within 72 hours and 72 hours passed I was told when the say 72 hours they count it by 8 working hours per day, a week passed and when I call their call centre I get a new consultant who tells me that they need lease agreement which I attached during my application, so every time when I call or send an email I have to resend my lease to every consultant I'm communicating with, it is the 27th of November today from the 13th of November and nothing concrete has come up , but other people within the same estate when the apply their lines gets activated within 72hours I'm so irritated and frustrated with this bad service .
