Suzuki fourways

On Monday the 1st of May,I went to Suzuki fourways,I have been servicing my car with them since I bought my car,it’s about 4 years now. The person who usually assists me wasn’t at work, whom usually asks what problems have I been having with the car and if I have any issues etc. checking the car and asking if I need a ride home/work. This time around I was assisted by the rudest colored lady I have ever encountered. Her attitude sticks and I hope this matter is taken serious,she didn’t greet me,started by asking me to sign and when I asked her why she goes straight to the money or break down the quote for me,she started getting even more irritated with me. Threw her toys everywhere,very unprofessional and unpleasant woman. She then grabbed my car keys and went straight to my car, opened it up (cabinet is a sensitive and private place in a car) but she went in without my permission. She comes back banding things around, calls the workshop manager Lucas to deal with me. I told him how rude she is,he didn’t bother to reprimand her. He had advised I come with a copy of my essential service permit but this was not asked for by this very rude woman or him. I am utterly shocked and disgusted at their service, I was so unhappy I asked for my car and rather book at another Suzuki. He went in a meeting by the time I left,they were not even bothered or try convince me to not leave,he didn’t not respond to my call or text. Please can this matter be handled soonest. Unprofessional and unacceptable.
