If the stocks are still there, then you are entitled to get them.

Unfortunately, there is no way to check if the stocks are really there. RH showed you some pixels on the screen saying they hold stocks for you. If RH maliciously or by mistake lost them or never bought them, then there is no third party that will make you whole.

Failure to deliver on borrowed/shorted stocks would be a conpletely plausible scenario during a short squeeze.
