Someone took money out of my account.

I checked my bank account today, someone listed as CCA on my bank statement. debited 99 dollars 3 seperate times. There is a phone number, it is after hours, so I will have to wait until morning to speak with someone. I did do the reverse phone lookup, and it said they were in Stockbridge, GA. The recording on the phone message said thanks for calling the benefits and card services dept. Does anyone know anything about this. Please ease my mind so I can get some sleep! That is 300 dollars that I need!!!!
