Disappointed in Service at Mr Price Mall of Africa

Disappointed in service i received today at Mr Price Mall of Africa. I purchased items paid via debit card cashier ran out of paper on terminal after payment went off from bank account he went to tills to reprint receipt came back with incorrect receipt helped 2 other people before ringing up my other purchases then didn't want to process items that my daughter had he told me that he has other customers waiting i asked him why did he call me out of the que knowing that i had alot of items in our hands. When i asked him again for the correct receipt they couldn't find transaction on his sales printout. I was told by store supervisor or manager that ibmust leave my purchases and they will call me back to the store to collect or refund my payment. I wasted 10 minutes in store while they we off line and another 20 minutes for them to check printout and tell me its not on their system and they can't do anything until Tuesday. It costed me extra to purchase other clothing items for a function Im attending later today as well as the inconvenience of money out of my account and if i need to go to another store i wont find items or sizes i selected today as well as the inconvenience of riding up and down and wasting my airtime to follow up with the store to enquire if payment went through or if they going to refund me.
