Disgusting customer service - store manager does not care how customers are treated

Game had a halfway sale on 01/07/2022. i went to the store to buy pots not realising it was an online only deal. Asked the manager if they cannot make an exception since I'm already in store in gateway game- she had an attitude with me from when we started speaking and she said no. i asked her since she's already online can she make the order for me because i didn't have my phone (left it at work) and she said no. There was only 1 set of pots left in the store. I went back to work and attempted an online order put my card details but the order failed. at this time there were 2 pots available. i called the store and informed them of my experience online and they said they no longer have the pots even online they are no longer available i told them i am looking at my pc and it say's there's 2 in stock which means there is an issue with their online site - i refreshed the page while on the call and it now said 3 in stock - as i was telling Bongani who works at the store i was now irate because i felt they are lying to me, he then suddenly says a truck just pulled up with more pots (after he told me the pots are finished even in the warehouse mind you) now suddenly because I'm irate a truck mysteriously pulls up with the same pots i wanted. I then told him there obviously is an issue online which would explain why my order did not go through so i will need to come to the store and buy them at the online price. i have proof of my attempts and considering the nasty attitude their manager had when speaking me. he said i cant i have to keep trying online. i went to the store and they still said no. Another manager Sanele came to the rescue between a heated conversation between myself and the manager with an attitude (she did not introduce herself so i don't know her name) sanele also said he cant discount it - i asked them to call somebody higher. they called the store manager Chris and he approved. The manager with an attitude went to get the pots and gave them to a teller telling her must deal with me because she has no time to answer to me - to this i responded to her i will send an email to Chris about her attitude - she said i can do whatever the hell i want and insulted me using my mothers name. I did send the email to Chris - the next day he responded by saying i can come to the store and buy the pots at the original price 999 (i already got the pots on sale for 599) i sent the email to express my disgust at the service i received from one of his managers and all he could say was i must come to the store. i now understand why that lady said i can do whatever i want because she knew she would not be reprimanded for how she treats customers. i am never shopping at game ever again.
