No I haven't checked for a number yet, I've got a name, bank account and address.  I've refunded them what they paid and paid for shipping, my mistake, in future I'll just pay the shipping and pay the rest once I've received my stuff back but I'm hoping there is no next time!

They wanted me to pay shipping before they would send it. I emailed last Friday to advise payment had been made and confirming our return address and when I heard nothing back I emailed again yesterday. Communication prior to this was good so I'm hoping it's just a case of them being on holiday. The account was only made in November (something I didn't notice till after) and the limited feedback they have so far has been positive.
