Query: Might be Good - I'll Never Know, Though

I've looked long and hard for light, non-slip slippers for my 90-year old mother. I ordered this pair from Silvert's, and instead of sending size 7 they sent size 6. I called customer service and they couldn't care less. They told me it was my fault for ordering the wrong size. I've bought over 700 items from Amazon over the past 10 years, and though some products have not been what I expected, I have never actually ordered incorrectly. There's no way they can prove it was my fault and not theirs, yet they would not waive the $9.99 shipping fee.Anyway, the slippers appear well-made. They're very cushiony, sole is flexible, and they're reasonably attractive. I'd buy them again (in the right size!) but I will NEVER order from Silvert's again.
