Bad service

Hi I had a very bad experience at Mr price mall of the North polokwane.i went there on the 19-03-2020 i was desperate looking for money for personal reasons,I went to manager(sello leope) to ask him if I could ask some of his client to pay for them with my account in exchange for cash... he then gave me the reasons why we can't do it because of process and procedures of Mr price and I totally understood the reasons.I am only human I know this things happen.I then decided to do shopping for myself instead I bought items to the total amount of R3000 it was not on one transaction but split transactions because I needed to relive stress that I had..I was with my frnd that time..when I was done with my shopping we decided to leave the store only to find out that there is one till slip that we misplaced while shopping because we had a lot of shopping bags in out trolley..we then asked the lady who was a gurd by the door to go back and check for it, she agreed. I went straight to the guy who helped me to pay for my last item, to ask if he can make me a re-print of the last item I bought. then manager came over to ask what was happening , the approach was very tens and very bitter, he started by asking if I went ahead with what I asked him earlier on which was asking customers to pay for them in exchange for cash, i then I said no to him I didn't because you gave me a clear reason why I couldn't do it..he then rudely continue saying he doesn't believe what I am saying, he then asked about the Mr price plastics I had with me if they were mine I said yes ..he then asked when did I pay for them and why did I make so much split payments instead of one..I gave him my reasons..he then started looking for the dublicate slip of items I bought.the cashier who was assist me stood aside because he was told to stay aside as if he was helping me to steel the product I baught since we cannot find that one slip..then manager checked on the system and he found all the transaction on the system of the things i bought but still insisted the That the cashier must give him all the dublicates till slips the cashier took.the manager started counting my items one by one checking if there was any item that was taken without payment..it was so embarrassing because I was paying with their own Mr price card that had enough cash to buy me a lot of things.people started starring at us as if I stole something in the shop,after that whole incident he then company us to the door for us to leave the store without even asking if we were done with our shopping but chasing us away and he didn't even bother to apologise for the scene and embarrassment he caused us...I am really not well with the treatment I received from the manger of Mr price mall of the north polokwane.what example is he setting to his team as a team leader? I mean if he gives customers treatment like this does he think his team will give good customer service to the clients?I really didn't expect such not after I spend this much at their store .tomorrow will I be able to go back and shop again at that store? I doubt.Mr price clothing manager is very rude not because of what he couldn't help me out with what I asked before I do my shopping.. but his attitude it's a huge problem.

Regards Very disappointed client
