Poor Customer service

When to Checkers Hypermarket in Brackenfell, bought a pan and a backpack. When we got to the tills,the price of the bac differ from the price where it was hanging. I waited for 15 minutes at the till for the department manager to come, i then asked to see the store manager i waited for her about 10 minutes to come. Whilst waiting for the managers to come about 5 staff members came to look at the product and made remarks such the barcode is not the same. He can't get it for that price.its not the same product.I will not give at that price. When the team of managers came no one introduced themselves I then asked the gentlemen if he is the store manager to which he rep**** no im the regional manager. The 2 ladies then left, I proceeded to explain the the regional manager what transpired and the service I received. It became clear that they already purposed not to assist or listen to my feedback. He said the price difference is too big and thathe can't give it to me for the price where the product was merchandised. I asked him for his name and their customer service department's contact details because it clear that he does want to assist. What was more disturbing was when we were about to leave the store, Ryno the regional manager, was jokingly talking about our interaction with his colleagues. Stating that he didn't give me the product of the price i saw because they are busy with a revamp and that mistakes happens. Just to be clear, the area where the product was displayed was full of stock the aisles in that section was fully stocked with proper signage even promotional ticketing, thus that excuse of revamp is weak. I am appalled by the service of the staff and especially the manner in which Ryno conducted himself infront of his staff and with his colleagues.
