I'm glad that they are at least going to let you return the bag...
The UPS thing would bother me though...My SS bag was delivered yesterday and I DID NOT have to sign for it!!! ....I don't understand why they were being so rigid with you about it. It was just left at my door along with a package for my DH.
NO WAY. Ugh.
They said when they deliver the new bag, I can send them a formal letter accepting responsibility, and then maybe the shipper will agree to waive the requirement. LOL
