This number called on August 10th and again on the 13th. Blocked

This is a telemarketing outfit, foreign accents, calling from a noisy room of telemarketing people. They knew my number, my name, my address. It's related to real estate. They previously sent me an annoying "We want to buy your house" letter. I stopped the conversation, told them I'm hanging up on them, and then blocked the number.

Annoying robo call. I haven't answered the calls

Caller said "This is a loan processing center."  I said, "I don't have time to talk right now."  They said,"Do you know the purpose of this call?"  I said "No. But usually it's about selling me something."  They said "We don't sell anything."  And then they hung up.
