Sizes unrealistic and very bad customer service

I am a size 12 woman. I used the Galaxy Army Navy sizing chart (which was VERY confusing) and chose a size large- very typical for me. When the shirt arrived, it was the same size as one of my daughter's Child's size Medium!! It is cut way too small for an average woman.When I called to get help from the company, our conversations were very frustrating. He cut off my sentences, kept telling me I had the correct size - "it has spandex and will stretch to fit", and that their size charts are accurate. (Although he had a hard time finding the correct chart to use, too! He was not willing to help or listen to my concerns. I was still willing to order another shirt so I asked for the "specs" on another style. Almost 2 weeks later.... no specs. A very frustrating dealing with this company....I doubt I'll get my refund...we'll see....
