Angry and dissatisfied customer from Pick ‘n Pay Bedford centre

I was at Pick ‘n Pay Bedford centre and a tv was priced 2499 smart shopper price.l, but when they scanned the tv it scanned 4499. When they check apparently they placed the wrong price on the tv. The manger was in store and he was informed about this issue. He didn’t even speak to me he just said “it’s not the same thing “. Responding to the cashier then he left because they said he was not on duty. I requested that he was called . He told me a bunch on rules I had no idea about. He then concluded to say it wasn’t the fault of Pick ‘n Pay but maybe a customer had placed the price. I even have picture of this .That tv has been priced like that since Friday 15:50 when I first saw it until Saturday 10:00. Clearly the person working in that department is negligent. To top it off I had already payed for my tv licence now I have a tv licence but I’m without a tv. Pick ‘n Pay will have to revoke that license under my name cause they are refusing to do justice. I feel like I’m being taken advantage of because of . Overall I’m so disappointed and angry. This is such an inconvenience. My right as customer was app****, what happened to the CPA rule? I will never set foot in that store again
