Disappointed clicks Silver Mall

I went to clicks Silver mall around 8:19 as it opens at 8am, with my child who happens be in a wheelchair, when I got to the till i was assisted by Mr Phathu who was professional also assisted me in moving boxes that were placed close to the paying till as the cleaner was cleaning the route to the till,what I was unhappy about was how 1 of the till cashier was asked to assist me yo look for special Nan pro milk no 3,he did not know the new package took his time to return back saying stock is done,when I asked if he can check which branch has he was not happy at all with my request,neither say I left the store without him coming back to me to advise which branch had the milk I wanted to purchase, also at the till the cleaner had her water bucket in the way of where my child wheelchair could stand even after making payment I had to remove the bucket and swift my child's wheel chair out the way without no one assisting,disappointed in the workers behavior especially so early in the morning cant imagine the service in the afternoon.
