Vumatel

I’ve been trying to reconnect my service in a new property that already has fibre installed.

Apparently the isp of previous owner still owns the line, but they deny it and i have confirmation that the service has been cancelled and a reference no for the cancellation

I have no access to the previous isp

Surely based on all this evidence vumatel can offer more asdistance than giving me the object no yet again. I cannot do anything with the object no, which i already have. How many calls does it take to resolve this?
