Deposit not paid and no communication from Thrifty

Rented a car on November 14 and returned it on the 16th of November, The guy who checked the car noticed a scratch and wanted to know if it was a new scratch or was it already there since it was marked or the receipt. I was to maybe it happened while I was driving there. No emails were sent to and it's well over the 21 working days period. Question is, will I be getting my deposit back or was it used to cover the waiver? Tried calling them all they did was transfer the call then hang up. You will caller number one on the que until u run out of minutes. It discouraging to see people still waiting for deposits from months ago. Please assist.
