A Shocking Experience!!!!!

Today my mom and I went into the Spar in Cambridge. The manageress' name is Wilma and the owners name is Graham. At this Spar on a Wednesday they get pensioners discount, but my mom realised that for weeks now she hasn't been getting her discount. So we asked about it and they said they've changed the cards and she has to get a new one and put her photo on it. So I tried to talk to them telling them that they can't just ask for a photo, where is the paper work according to the POPI act. They were not interested in giving my mom any paper work she must just give them a photo or a certified copy of her I. D. I refused so Graham came out and very rudely told us: "out of the goodness of his heart, he is giving discount to pensioners, he won't be allowing my mom to have a pensioners card from his Spar and that he is losing so much money doing this." All we wanted was paper work to make it official. You by law are not allowed to request documents like that without the owner of the documents agreeing in writing to this affect. I was horrified at how rude a store owner of one of the Spar franchises could be!!! Also for weeks now mom hasn't received her discount and not one teller has told her that her card is out of date!!!! She doesn't drive, so she only go when someone takes her to the shops and has wondered for weeks now why there has been no discount. Spar, Cambridge East London, I am very disappointed in the way your staff treat their valid customers. You obviously don't value your customers if the way you treated us today is how you treat your other customers. WHAT A SHOCKING EXPERIENCE!!!!!!
