POOR CUSTOMER SERVICE

Good day I would like to lodge a complain against the service I have received at MRP HOME in Westgate Mall in Roodepoort, Gauteng.I normally buy my things at this store and in most cases I received good service except for yesterday 29/04/2021. I went into the store around 17:30 and went back to my car to fetch my card when I came back I found that the doors were closed and only one slide of the door was kept open at around 17:37.I choose the bed covers and sheets and I was not aware I chose flat sheets instead of fitted sheets I had to go back to chose the right ones and when I left the till Maria advised me I must not take all because she wants to cash up.I went and couldn't find the size that I was looking for for sometime,one guy came and told me they are running out of time I'm the only client left I must get what I want and go to pay.I asked another guy in the store to help me and the same lady by the name of Maria with a name batch supervisor,came to me to rush me and told me " lady you need to choose quickly you are the only one left in the store,I have to cashup, hurry and it was not even 17:50.She stared at me and kept repeating herself.I had to decide quickly as I don't have time to go back to the store and I needed those products.When I get to the till I'm taking out the card she says the machine is not working and when she returned me from the till she asked if I'll be paying cash I said yes and she did not specify whether she is talking about hard cash or not and in my understanding if she says how are you paying its either cash or account irrespective of card or hard cash.I had to take out hard cash.I had to walk out of the store unhappy. And no one bothered about apologizing. The doors were closed before six.I walked in before 18:00 but I was treated like I'm a burden. I work in a bank I know about customer service and I know about cashup.clients come first,papers comes last.But in MRP HOME paper comes before people. The same people who keeps the doors of the store open.My concern is that the main person who gave me poorest service is the same person who is regarded as a supervisor in the store.Customers must be treated fairly and with respect.
