Wrong pricing on items in store

I live in Bluff,Durban, I was visiting in Balito on 13-07-2024 and visited Balito Junction mall. I decided to go into the Hifi corporation store at the mall to purchase an iron and a toaster. I chose a Phillips iron which had a price tag of R449.00 and an Orion 2 slice toaster which had a price tag of R299.00 on the shelf. I used my debit card to pay for the items not realizing that the prices on my receipt were not corresponding with the advertised price on the shelf. When I got back home and looked at the receipt I realized that they had overcharged me for both items. I contacted the store and told them about the issue. The next day I returned the items to the store with the receipt and the prices were reduced and the balance paid back to me . I had to travel almost an hour to the store just to resolve the price issue which I was highly upset about because I had to cancel my plans for the day and also had to pay for fuel to get there and back home.
