did not accept either of three options given when my insurer

had accident approximately 9 months ago. Had full coverage with State Farm(GA) . Car was considered as totaled and I was given 3 options. I did not want to give up my car and was told to put it in writing [which I DID NOT DO]. I have since been convinced to take the salvage option and not drive it for 6-8 months. since I did not put it in writing can I still take this option? with my insurer state farm in GA
