Avoid the poor service and this complete lack of customer centricity

I recently purchased a jersey as a Christmas gift for my brother, only to find that it didn't fit. Hoping to exchange it for a larger size, I visited the store today with my brother, who is visiting from overseas. Despite having the intact tag and recalling the name of the employee who sold it to me, the staff refused to assist without a slip. I expressed my prior inquiry about the exchange possibility, but the response was a flat-out 'no.' This lack of flexibility and customer service left us disappointed. It's disheartening to feel disregarded, especially when alternatives, like checking with a manager or exploring options, were not considered. As a result, I'm left with a jersey that doesn't fit, and the overall experience has made me reconsider future visits to the store. It seems the store missed an opportunity to prioritise customer satisfaction and adapt to modern retail practices.
