Disgusting service

Since bought my corolla at Maponya in 2014, I have always serviced it there and bought parts and fitted them there. On the last Saturday of Novemeber this year I have received the most disgusting service from there. Came in at 11 am and found the only lady to help me was busy with her colleagues. Waited for her to finish and eventually she was on the phone while I stood there waiting. Only when making eye contact with her she asks if she can help. I asked how much it would cost to fit a bumper and she qouted R1039 which was shocking and then I asked why it was that expensive. She unfriendly said she will speak to the technicians and then I waited. Few minutes later I could hear her and her colleagues discussing me. Loud and clear speaking seSotho. She eventually came back and did not give me a verdict. Me being worried that they are about to close soon I follow her to her to her desk and tell her I may have to fit the bumper some other time. Then I asked her to give me a quote and write it down with her name for reference. This time the technician was there. The same one I over heard discussing me. He tells her to quote 2 hrs and when she calculates and comes back with R1485. It doesnot make sense. In a matter of 40 minutes the price had gone up. Not only that but them discussing customers like they did with me is very unprofessional and beyond disgusting. I am used to a few faces there wit good service but this.... I was seeing their faces for the first time.
