Horrible customer service/refunds

I’m livid appalled is the understatement for the treatment of customers by management and workers there I purchased a wrong item where else I wanted one on special sent my son to exchange the product unfortunately I didn’t know the extra savings card was going to be needed for the price to resemble the one on sale son came back with short money from exchange I went to store waited 2 hours without assistance taken from pillar to post without any help a rude supervisor called Agnes said I should come back today and went back can I tell it was as if I had no communication with her the previous day acting superior like I owe her something with no sense of professionalism and she disappeared on me instead of helping me I grew tired and left I want to tell you those managers and supervisors they need training because what I witnessed they lack it dismally they don’t care about customers satisfaction only do as they please without being reprimanded.
