Letter of complain

I'm unhappy with the service I'm receiving from Clothing Junction Thabong.

Last time I purchased clothes for my children, they were the wrong size. I returned to the store after 8 days to exchange them, but the cashier, who has light skin, tattoos, and a beard, refused to assist me. When I asked why, he said it was too late, which I didn't understand since it was within the 30-day return period. I chose to let the matter drop.

However, this Monday, February 26th, I returned to the store and encountered the same individual. As I was about to purchase a T-shirt, he took it and stated that he was 'hiding' it for himself, intending to purchase it over the weekend.

I'm concerned that staff members are reserving items for themselves, potentially preventing other customers from making purchases. I'm unsure if this behavior is representative of the store's overall service or just this particular employee. Could you please clarify if I'm misunderstanding the situation or if there's an issue with the staff member's conduct?
