Unsatisfactory resolution from Best Store Exchange

I'm writing to complain about the training session I received from Best Store Exchange. After paying $111.54 for unit, I found that it encountered rude staff. I've tried resolving this with your customer service team multiple times, including speaking with Breana E., but have not received a satisfactory resolution.
