Dear ____. Yes we sent you the , add your description of the camera. Please check if you have confused us with another purchase from another seller. If you have received a radio, we will be filling an insurance claim with the USPS, or whoever. Keep all packing materials in the event that the postal inspector comes to examine the package for tampering. Now in reality, when a buyer makes a false claim like this the cases are most of the time slanted in the buyers favor. They really do not need to even show any evidence most of the time. You have to be careful here because there is a remote possibility that they have confused you with another purchase. Be polite, factual.
If they start a claim then respond to it immediately. Return for full refund. Get tracking info from the buyer when they send it back. If no tracking I advise you have your mail held at the post office for a few weeks so that when this package comes back you can ask for the assistance from your local P,O, where they can weigh this package and then witness the contents of it as you open it there. Postal worker can sign off on "package arrived empty", or "package arrived with whatever in it".
Report buyer to Ebay for misuse of the buyer protection policy. You can call them again and ask what to do next. You are probably going to encounter a response such as. "we cannot determine what you actually sent to the buyer" maybe not but that is what usually will happen.
If no helpful or useful response from Ebay , then you have to determine whether the cost of this item is worth filing a small claims case against the buyer, and to report MAIL FRAUD and an IC3 report on the internet for internet fraud.
You can message the buyer stating you recieved back ---- and sent ----, and will be filing the reports. Sometimes the item comes back magically when you do this. Best of luck.
