Utter Poor and Unacceptable Service Ever

We app**** and was approved 1week ago for fiber service, the fiber line was installed and the fiber router was confirmed as being operational and active, two day later we received the Tenda Router that is to be the interface unit for the Vuma Router. We have logged three calls, sat on the phone with technical support for almost 2hours at a time just to be told there is an interface problem with the IP addressed of the Tenda Router and Vuma Router, we have e-mailed through the comand prompt IP config screeen shot twice and where promissed that it would be resolved today again we are told just to wait as it would be resolved as there is no turn around time for IP Config errors to be fixed. This is possibly the most unacceptable service received from support service staff that clearly has no Programming or Trouble Shooting experience to start with. We have cancelled and await the money to be back into our account by the 28th December 2021 and we insist on all this no usable equipment be uplifted with immediate effect.
