Checkers you lost not a sale but a customer

I went to checkers at festival mall to buy a kettle today the 5th of June on level 3 lockdown... I got there and liked this one kettle by platinum for R290, unfortunately it was the last one but I really liked it. So I went to information desk with it, n I asked to test it for me since their policy is if you buy a product on display you can't exchange or return it, and I was Ok with that. Was sent to Deli to ask for water so they can test for me and I did, even offered to take the container used back to Deli after testing. Kettle was fine and I negotiated R250 for it, finished my other shopping and went to the tills, only to be told that I can't get it because apparently head office has instructed them not to sell products on display... I was so disappointed, after all the interaction in this covid impacted time, I wasted my time and risked my health for nothing. I left even my other shopping in their trolley there n there... Not only have they lost a sale, but a customer as well. I will find another kettle else where...
