Boots pharmacy - Bad customer service, bad people

I was using this pharmacy when I faced many negative things: 1. You cannot return the medicine or goods you bought from this pharmacy. They do not accept any returning. This is unacceptable and against international business rules. 2. One of their customer service person has a discriminating behavior toward customers. Once I was in their store and his seller told me that I didn’t sell the medicine to that guy because I didn’t like him. 3. They try to sell you the medicine which its expiration date is close. Once I tried to change the medicine with the one that had longer expiration date but they wouldn’t let me. You cannot choose some medicine and they try to sell you those medicine which expires soon. 4. This shop is very very expensive. I am not shopping from this store anymore as they behave bad toward customers.
