I had a similar issue on a rv camera. Couldn't get any responses, when I gave them 24 hours to provide tracking info, they shipped out some junk. they attempted to give me the run around on return and refund... but when I started quoting their own return policy, they made one last attempt at rationalizing why they wouldn't refund... cut and paste from their website did the trick, stating even tho I didn't return everything (false), they were issuing the refund
