I just answer the caller in a friendly and indifferent tone of voice saying "thank you for calling domino's pizza could you please hold?". Nine times out of ten they hang up. But in the rarest moment of exception I patiently inform them that no this is not fuckmart. If they get even nastier, which is a very rare occurance indeed I inform them that soonest delivery available very long time as a failsafe of course.
