Called 3 times at my office and I didn't answer as didn't recognize number. Finally answered yesterday at noon. Offshore call center where they want to send you a white paper (some technology related item as I'm in IT). They called again today after I told them not interested yesterday. This time I answered and immediately said, take this number OFF your list. She said "who am I speaking with". She called me so I said, "who are you attempting to reach", she asked who am I speaking with. No lady, you CALLED ME. Then I asked, what company are you with that you are calling me from, she again asked "who am I speaking with". I again said, no, you called me so want to know what company you represent and then she hung up.
Sure, we'll all tell our VOIP teams to provide phones that can block numbers. Apparently you didn't see the comments above saying this is a scammer targeting businesses.
Indian lady (Dots not feathers) called. Could barely speak English so I asked her to send everything she has to my Ex-wife's address. I also gave her my Ex-wife's number for future reference. There's always a silver lining...
