Definitely report the seller to EBay for investigation. There's something very wrong.
I won a sewing machine on EBay for a pittance, and the seller promised to send an invoice with shipping in 3 days. On day 4 I sent an email and was told by the seller I had backed out and the machine had already been relisted for much more!!!! I requested a copy of the supposed final invoice I never received and the purported notice from EBay that I had backed out- and they didn't exist. I made sure all contact was through EBay- none on my personal email. Finally received the machine and the attachment tin was damaged and the footplate was missing! I sent a neutral email asking for it and mysteriously it was "found". Seller had an excellent rating- apparently just perturbed the machine only had a few bids. This wasn't a valuable machine- just a sentimental one for me. Not worth the hassle but it was the principle. Your seller sounds very deceptive from the outset. Hope you get your table!
