Vuma Fiber extreme lack of customer service in Newcastle

My partner signed up for fibre installation and connection. Payment was made on the 14th March. He got a reference VR-0***- with a password. Since the payment was made, no one has bothered to contact him or install the fibre as per request. He has made numerous calls and today being the 1st of April, called the landline and was told to call via WhatsApp (mind you we are still waiting for internet to be connected). He has been told that they will get back to him. 15 days after payment and still no communication or installation done. How does Vuma fibre conduct their business. This is pathetic and shows really poor customer regard.
