last week was new year week, so it may be a delay. For example:
I have ordered HID set from DDMTuning on 15th of december.. After waiting 2 weeks, tried to contact them any possible way, no luck.. Was ready to cancel my CC transaction, but 3 days ago received tracking number, should have the kit in 2 days. It was really cheap offer, DDM kit for a $60 shipped, or so.
But, not responding to a PP claim looks really strange.. May be they are russians? Still might be drunk form a new year party, wich last not less then 1 week :-)
