Proof? an envelope marked "return to sender" I guess. It would have to be addressed to me at the correct address or it would have a Post Office change of address lable on it. how else could they prove they sent a check and it was returned?
Thanks for the replay.
I Did not receive my deposit within 21 days per CA law.
After about 35 days I began to visit and call the manager/owner. I was told the check was mailed but never cashed. They had a forwarding address and a change of address was put in with the PO. All my other mail is being forwarded...
