Bad service given

I am writing this on behalf of my 64 year old pensioner mother. On 05/05/2018 she went to the Promenade branch in Mitchell's Plain and stood in the less than 10 items queue for about 20 minutes, as she did not realize that it was only for 10 items or less. When she got to the pay point, she was not greeted for number one and was abruptly told by the cashier, Beverley Randall to another till point. My mother did not mind doing so but was disappointed in the manner she was treated as she is a valued customer of this store on a daily basis. She then had to request the cashier to return the items back into the basket but was then declined to do so. The service is this store in particular is pathetic to say the very least. The cashiers do not greet or even make direct eye contact with you as the customer, the one who pays their salary. Please assist as my mother as well as all customers has to be treated fairly and with respect.
