How to complain about rights protection? It cost more than 4 thousand to take wedding photos at their home. I don't want to recall the photos two months ago.

If the studio is busy in the peak season, it will take half a month for guests to take pictures. After filming, they have to wait a week to choose the film, and then wait 30~40 days to pick it up. Generally, this is the process of the studio (if the guests are in a hurry, the process will change). Please see if your studio can produce a film after this period of time. If so, defend rights. They probably deleted your photo by mistake, which means they took it for nothing.
