you reply back with "je suis desole mais je ne parlais pas beaucoups de francais" which translates to something like "I'm sorry but I don't speak very much french" (it's been about 10 years since the last time that I spoke any french with any regularity, so my phrasing may not be 100% correct.) If you do want to continue in french, you can also throw in a "lentement, s'il vous plait" which means "slowly, please."
