Total fail in service!!!!

I reset my P9 lite but had forgotten the google account details. I was referred to Canal Walk service Centre by a call Centre agent. I went to Canal Walk , Hauwei and was told that I need to bring the cellphone between 9 and 5 when there technicians are on duty. Fair enough, the following Friday I rushed from work to arrive at the store at 4 pm. Stood in the line for 35 minutes because they only had 1 person assisting customers but a bus load of people in the back. Made me some complimentary coffee and the milk was sour:(. Was finally helped and was told that it would be done immidaitely and the cost is R150 and it would take 10 minutes. I made payment and waited another 45 with no creason communicated from the staff as to why!!! A lady who arrived after me, MRS Kiewitz a family friend who had brought a P9 lite with the same issue was helped and not charged R150 , what the hell!!!! She left way before me as well. I was then told by a young lady that my phone does not pick up on the computer and that I must collect the following Day, Saturday. Due to illness I could get to Canal Walk the Saturday however went on the Sunday.....and guess what!!!!!! “Sir your phone was not worked on”....this is the worst service ever!!! And lastly the shop was filthy! Service tickets laying on the floor, the same paper cup I had used to make the “coffee” the Friday was still standing at the coffee machine, the sour milk as well.....
