Bad service!!

I have been servicing my car at the very branch for the past two years and never experienced problems until recently. I went there three weeks ago citing the challenges I had with my car radio, and got a black gentleman at the services desk. To my surprise he was really not welcoming I don't know weather it's because of Covid or maybe I am mistaken. He barely acknowledged me didn't even offer me a seat, okay moving right along. I explained the situation to him and he made a booking for me that following week on a Tuesday 23/06/2020. I then called on the 22nd to reschedule my booking and we did that for the following Tuesday the 30th. I then went on the 30th early that morning around seven and he tells me that the booking was for Wednesday the 1st I must have been mistaken. No apologies non whatsoever and he carries on with other clients. So you tell me what kind of service is that? I woke up early that day, requested time off from work only to treated like that.
