Call every day from a variation of this number. many days multipole calls - both live people and robocalls. I have reported them several times to the FCC and the National Do Not Call List.
in past 8 days, I'v got calls from 770-824-8547 twice, 770-824-8546, 770-824-8552, 770-824-8550 wice, 770-824-8568, 0704, 8540, 8575, 8541, 8545. Many more time prior to the last 8 days, My caller id only records 25 calls. I no longer answer these calls, because then only time I did, was asked if I could hear them. Without thinking, I replied yes, and hung up immediately.
