Best Shapewear

I ordered the Slimming Thermo pants and ordered a size Large... I typically wear a medium but wanted to be safe than sorry... I received size small. When i contacted them to tell them they sent me the wrong size, they told me that there is no refund for wrong item. A few weeks later, I did receive the size large, but it was ridiculously small and they would not refund my money for this. They say guaranteed satisfaction... but NOPE... not satisfied and no money returned.

I purchased the High Waisted Shaper Shorts, $19.95 on 12/14. Item arrived, did not deliver as promised, fit like pantyhose without legs, no compression at all. Told them I was not satisfied, they offered to exchange for the Slimming Thermo Pant, $19.99. On 1/5 they informed me that the Pant was. 04 more than the shorts, therefore they could not exchange. 2/6, I decided to accept the Ultra High Waist Shaping Panty.
Their continued response is "we are sorry, we want you to be satisfied, please be patient, your order will be shipped in 7-15 days. Today is 4/11, I am still waiting for my replacement. I also requested a refund.
