Overcharge and unprofessional service conduct

Wish I never stumbled across them. Worst service ever. Please don’t use them. Stuck with an invoice of R4500 just for a connection from the living room to a tv in the room. When querying about the invoice, they are not willing to discuss my questions or even hear me out. Very arrogant over the phone. Also put the phone down in my ear. Wish I could rate 0 stars
