Police officers threatening to kill me

I would like to open a case against Capitec bank that stole my R5000 and accused me of *****, ******* and theft. I tried to open a case with SAPS Midrand but I was forced into a detention cell, ***ually humiliated with later led into gang **** perpetuated by a police officer deliberately. I tried again to open a case with them but I further abused threatened to be killed by police officers. I fear for my safety.
