LIPOELASTIC® VH Special Comfort - Post Operative Compression Garment

I first bought a Lipoelastic VH with zipper at both sides, the pain it caused me was as bad as the surgery itself. I then purchased two of the same items with no zippers they both felt slightly more comfortable.However the 3 items have a common denominator, they are not long enough. Their bottoms feel like wearing a thong and I hate thongs. In fact it is worse because their tightnessess are extremely painful. So pain at the top and pain at the bottom. I could not return them because I had already worn them.I telephoned customer services for advice, the lady that answered the phone said that they were too busy to help me with my enquiry. I then emailed, their reply said that people had different sizes, stating the obvious really and that I should buy such and such product.The trouble is that I have already spent close to £300 pounds with them on post surgery care.
