Repeated calls do not end

I have been getting phone calls from this company for weeks. About 3-4 times per day and it is automated. Today I decided to answer yes to be transferred to a person. The guy who answered said he would remove my number and was very sorry for the inconvenience. I verified my number and he said he would add it to the do not call list and then he asked me WHAT COLOR MY PANTIES WERE!!!!! And because it was totally random, I said "excuse me" and he repeated his request 3 more times.
