Professional Medical Supply

Purchased diapers for my father before buying it I asked the employee what is your return policy and they said as long as it is not open when can return it. I came back 2 weeks later with the product and receipt not open and they would not return it because it is more than 7 days and she said it is on the receipt with very fine print. I asked to talk to a manager and the manager refused to come out and talk to me. Then I got upset, then one of their employees picked up the product and told me to get out. This place is very unprofessional, and the employees are very rude. If I had not asked the employee what the return policy was then it was on me, but I asked and they did not tell me. I don't think it is my fault to lose that money. I want me money back.
