Burgens unprofessional and *********

I requested a quote on my Samsung washing machine and a technician came on site and stated that he suspects the bearings need to be changed and stated that they will send me a quote and they then took the machine away,I then received a quote and hour later for an amount of R1660 and there was a quote number and it stated 2 x bearings and oil seal needs replacement I have the go ahead and they even gave a thumbs up.I received a call from a lady from that branch stating that I need to pay another R1200 for another part,she was extremely rude and stated she owned the store which I found out later was incorrect,I called the owner John and explained to him the situation to which he initially agreed then he calls me back and takes his staff part stating that they do initial assessment which happened and then further assessment which is a load of **** as why would you provide a quote and then give a further amount this is ********* and unprofessional...please don't Burgens yoi will regret it,unprofessional and ********* behaviour!!!
