I have received multiple calls from this number also ... telemarketers, outsourced

Been calling everyday for two weeks. Indian lady. Did not identify herself, asked for owner each time. Everyday I say, he is not in. Calls again next day or twice in a day. Every day! Finally I got sick of it. Said "I am owner how may I help you?". As I suspected, is a Visa/MC telemarketer. After I told her, "we are not a business, we do not deal with money". Says OK, hangs up. She calls again 10 minutes later! And starts asking for the owner again. Same lady. Has no clue that she just called me 10 minutes earlier. I give her the exact same story from 10 minutes earlier. Says, OK, and hangs up again. Hopefully for good this time. Odd. Could be sitting in India, I suspect.
