WORST SERVICE, ******* AND DISHONESTY

As I'm typing this I'm so angry and not happy with their service.. I took my car for service and they decided to take all my money in my car!! The only job they had was to service my car. Also why was my car not washed? And this is the 2nd time, last time I was told to come the following day they will wash it🙄. I sent my complaint via what'sapp and I was told the manager will give me a call back, till this day I haven't received anything from them...
