Power Sellers Digital Broken camera suppose to be new Internet

I purchased what was suppose to be a new Nikon 2000D. When it arrived it was not packaged as a nikon should pe packed and there was no Nikon Warrenty. I called and they assured me it was a new camera.  They sent me a generic warrenty. My husband bought me a new lense and when I tried to take a picture no pictures would record on the camera. I called and they gave me an address to return the camera. I packed it and mailed it to the address they provided. I decided I should notify my credit card company because I had a very bad taste in my mouth. The camera was mailed priority mail on 4/25 and insured to the address they provided. The camer was returned today 6/17/17 with return to sended not with undeliverable or no such address. This is a very nasty company and is not a legitament honest camers dealer.
