this is the name and address that Kevin Stone (so called customer services supervisor) gave me a while back for my ongoing problems:
Ebuyer UK Ltd
PO BOX 3189
(Mike Naylor is supposed to be the MD)
didn't help, mind, sent a number of letters ages ago, i think all complaints go straight into file 13 if you catch my drift...
still waiting for a response and resolution, but don't hold your breath!!!
