Sorry you're having a rough time with them, but a lot of people (myself included) have had an excellent experience shopping there. Personally, I ordered an R4 on Jan. 2, and it was shipped with no problem on the 5th. It arrived a week later, perfect condition, everything working as it should.
Your expectations are sufficiently low to think that was acceptable.
I ordered my M3Simply from
http://www.modchip-store.co.uk/ at 10:30 in the morning and the postman delivered it to me the following morning at 8:30 am. I know they are in the UK but there is a marked difference in the service level.
Why did it take them 3 days to ship your R4? Why did it take a week for delivery?
