Woolworth's Dainfern - Terrible Service!

I shopped at Woolworths Dainfern Square on the 1st of March firstly the cashier tripled scanned some of my items my bill came to R1005 for about 8 items. As a customer that is very conscious and aware of my spending I ensure I know +- how much I will spend. I told the cashier please can I see your screen as you scanned items twice or thrice. She ignored me and my bill was then brought down to R860. I was still not happy and I then asked again to see the screen which she now allowed me to. I showed her which items were double scanned. My bill was then brought down to -+R600 I paid for it and as she gave my my till slip things still didnt look right I went back and showed them that they doubled charged me for the tray of lamb! The manager was there and she then refunded me R103 for the lamb. As I walked away I realised they double charged me for another item this is now the 4th time I'm going back the manager asks me arrogantly "what do I want now" I explained and she refunded me R41.00. I was patient as I kept going back for MY MONEY. The level of service that i received was pathetic. How many other customers do you over charge without them even realizing it??? I shop at this store almost every second day. You do not treat loyal customers that way and then be rude when you are at fault! There was no apology from the manager as I walk to the front of the store I walked to the security and asked to speak to the floor manager to which I explained and he apologised and offered me a bunch of Rose's. I declined I am not looking for freebies! I expect to treated equally as other customers and I expect to he charged correctly for items purchased! I haven't recieved my money yet nor was an expectation or process explained to me. I am an extremely disappointed customer! The service you provide is what sets you apart from the rest of the retail providers that I shop at and unfortunately you did not live up to the service you PROMISE to customers
