Everytime uncertain

Me again. I'll keep on complaining, till things get better!

Pick n Pay Kempton Square:

For the past mont or so, I got different tillslips when I pay for my stuff by card. Everytime the cashier gets confused, and everytime they call the manager/supervisor, and everytime the person in charge accompanies me to the security, and tell them that it is okay, I can check out. Everytime I ask them why, and if this is only happening to me, or to other customers as well? Then everytime they tell me that I am not the only one. This has happened now, for about the TENTH time, with different bank cards of mine. Can't they inform their cashiers and staff about this "problem", and or find a sollution for it? Why must I wait everytime for about 10 minutes in a line to pay, and then another 5 minutes to ask the supervisor if my slip is okay, then another 5 minutes for the supervisor to tell the security that I may pass.? Just sort this out already, please? It's been too long now!
