Rude unprofessional driver

Drivers doing as they please and making clients uncomfortable by sticking his nose where it doesn't belong , he questioned if my delivery address is my property or rental and even when told its mine he still didn't believe it. Claiming I might be *****ing Vodacom , the nerve and disrespect for the company he represents and Vodacom ! I mean if Vodacom didn't ask me anything related to owning/renting ,how is that his business as one doesn't even know if he's asking for business concern or own interests :( but because they are never held accountable for their actions he went and **** that " client no longer interested " & order cancelled ! What the f#&*@ , who takes time off to await delivery off their busy scheduled to be played by your rude unprofessional drivers . Fix it please K***
