Constitutional rights violated?

I was detained for supposedly stalking, then handcuffed and put in a car. I was brought to a police station, and questioned, about the stalking which would end, then questioned about keying a car. I answered questions that would incriminate myself however was never read my miranda rights, and although only "detained", I was handcuffed and I believed I was in custody. These are both in violation of my fifth amendments rights - custodial interrogation, my miranda warnings, and no self incrimination due to my signing a document that said I did something. Were my constitutional rights violated and if so what can I do?
