Worst company ever dealt with!

I waited on hold for 17 minutes just to speak with someone! I immediately returned the keys and was told that I would have to wait 30-45 days for the credit. Now I'm being told I have to wait another 30-45 days from July 1! Worst company that I have ever dealt with! Will never buy their product again! I will be contacting BBB! I will say that Amber was wonderful and very helpful!
