Pathetic attitude displayed by management

Disgusted at the attitude and behaviour of a manager employed at H&M gateway (South Africa). I bought a top from the gateway branch, I didn't notice that the one sleeve of the top had foundation marks, evidently from customers trying on clothing. I attempted to return the item on Saturday, 14/01/2018, however I was met with pathetic customer service by a manager by the name of Rico. He refused to accept the product in the original state that it was sold to me, as it had foundation on the sleeve. He told me that the store does not sell products with foundation on it, and if they do, they offer the customer a discount. He imp**** that I was lying as he repeatedly stated that the store didn't sell me the top with make up on it. I asked him for his name and he sarcastically and mockingly spelt his name extremely slowly, as if I was incapable of understanding him. I fail to understand how this store has no problem selling products in this condition, yet has a strict no return policy in place for the same reason. The top had the tag still intact and was clearly not worn. The behaviour displayed by this employee is absolutely shocking, and I will not be supporting this store in the future.
