Calls every 15 min, doesn't leave message. If it's so important to call that frequently, they'd leave a message. Time to block!

I agree with Tammy.  It is absurd the number of calls that I receive from this number!

Yesterday they called at 841, 1004, 1111, 1124, 1231, 201, 311, 343 and 756!  Today, 846, 1044, 1141, and 149 so far.  I wasn't home for all of the calls except for the last one. Answered the most recent and they asked for my roommate. When I asked who was calling they proceeded to say my roommate's name and that this was an attempt to collect a debt. I advised that I wasn't that person and they asked to speak to them. When I asked again who was calling, they said it was a personal matter. I asked to take a message and they refused to leave any info and said they would call back and hung up. Guess I need to turn my ringer off!
