Vumatel- Poor service delivery

I purchased a property and the move was planned for the 30th October. The previous owner removed the fibre box and a new installation was required. My internet service provider has charged me for the new installation but to date I am not yet connected. Vumatel initially got my address wrong despite me sending a number of e-mails and have been unable to either clear an existing line to install a second line. All it requires is for a team to come onsite to have a look before proceeding with the installation. Vumatel blames the internet service provider and vice versa.
