OOOhhhhhhhhhhhhhhhh dear, will people never learn! Tip-never but from ANY company that hides behind email and that you have no other way of contacting.
To be honest, get an RMA number, return the goods and insist on a refund. You will probably have to push them hard and it is likely to take at least 6 weeks. You should get there in the end.
Check out previous threads for tips if you have a problem, then do as I do (from past experience )and buy elsewhere!
