Pick and Pay BAD service

My fiancé and I went to Pick & Pay Wondwrboom junction yesterday and AGAIN had a VERY VERY VERY BAD shopping experience! We picked our items and went to the tillpoint to pay for them, I advised the cashier that I will be paying with my Pick & Pay account card....swiped my card entered the pin and transaction showed 'Declined' KNOWING I still had enough money in my account the cashier asked to swipe my card again so I did did everything all over again and again showed ' Declined'. I then asked for the manager which they called....I explained the situation HOWEVER her first reaction was that I must pay with another card and not being friendly at ALL. We went to her office and after a whole discussion she opted to call RCS customer line but she just took their word as what they told her and that was IT! I then asked for any senior manager number and she EVENTUALLY gave me her Divisional manager number...first his phone went to voicemail and I called 3 times and found voicemail....I called a 4th time and then his phone rang and he answered (Bare in mind not even calling back at any given time)! I explained to him the situation and he just said it is not Pick & Pay fault and we must JUST wait a few hours for the money to be reversed etc....NOT even opting to assist with RCS to try and resolve the matter in any way. We needed the groceries but we had to JUST take it like that WITHOUT our items and leave empty handed. As a PAYING customer in which ever way I pay being ABSOLUTELY DISGUSTED with how I was assisted AND had to call RCS on my cellphone and pushing up MY bill, even the Divisional manager asked ne to give MY phone to talk to the store manager WHAT THE HELL! I am FINISHED buying ANYTHING again at Pick and Pay!!!! I will also share my BAD BAD BAD experience with Pick and Pay with ALL friends,family and work colleagues!
