++++Resolved+++ Beware this UK vendor

I will doubtlessly get Banned for posting this however if it is posted it may stop others from being caught the same way!

About February this year I placed an order for 8 EK waterblocks to fit AMD5850 Reference cards. The vendor WaterCooling UK had 4 in stock and agreed to try and order another 4 direct from EK. Because this was a special order Watercooling UK asked for upfront payment which I paid a total of 353 UK Pounds. It transpired that EK factory had stopped making the 5850 Blocks so Watercooling UK were able to supply only 4 from their stock and not the original required 8. We renegotiated prices, I agreed to take some other items and there was left a balance of 140 UK pounds to be refunded to me.
By now you can guess where we are going with this, of course Watercooling UK have now stopped answering E-mails Of course because the delivery took so long I am outside the PayPal 45 day limit on refund transactions. So it looks like I am out of pocket to the tune of about US$240.
Frankly I am very surprised by this, they seemed to have a good reputation, however there is no mistaking that they are now deliberately not answering e-mails so you can draw your own conclusions from that.
(I can provide an e-mail chain to support everything stated here!)

Forewarned is Forearmed

EDIT:- +++++++++++++++++++++++++++++

This matter has been resolved. Once this matter was brought to the attention of WCUK they made every effort to resolve it promptly It appears this was a genuine oversight caused by separate issues with the WCUK Web site and e-mail system that caused the lack of communication. WCUK have now fixed those IT issues and this kind of problems should not re-occur.
The high level of confidence in WCUK is shown by the number of people who posted their surprise at my initial post. While this has been a PITA for both parties involved the outcome shows that the confidence expressed in WCUK is not misplaced.

Thanks to Moto for forwarding the initial post on to WCUK.
