I've just had to open up a PayPal claim with these guys.
Initial service was very good, ordered a EMG / Strike Industries ARK, item marked as in stock, provided the service to break down and ship parts seperately to alleviate customs woes.
Two days later I was emailed and told item wasn't in stock (still showing as in stock on their website) and that I'd have to wait 6-8 weeks. Responded asking for a refund, no response. Chased a couple of days later and was told their policy was to only refund within a 7 day period of initial order, strangely enough I was now outside of this period....
...well anyway, I was then asked to take a store credit, which I declined, and now they haven't responded to my emails requesting a full refund.
In my view, they're keeping the money until PayPal remove it from them. Pretty shady if you ask me...
