Most disgusting service ever!!!!!

The worst admin service ever, The written quote was different from the verbal quote by R800,00 more. It was a mission getting someone to send me a quote with the correct details. Signed the quote and made payment and the windscreen were fitted. More that a month later I was told that I actually short paid. And their guy is fighting with me and threatening that if I don't pay in 7 days they will come and remove the windscreens. I am so disgusted with this service, I will never in my life use them or let anyone I know use them again. You guys are the worst and you suck big time.
