The exact same thing has been happening to us- some lady named Stony. They've been calling every day a few times a day asking for the owner. I asked where they were calling from and she did not respond and simply hung up. Very annoying and disrupting to our business. Told them multiple times to stop calling!
Not only they called me multiple times, I never answer the phone, I blocked the number... they also can go over my blocking call system and even answer my own phone without me touch it, and in addition they can even activate programs in my phone...isn't this weird . These people are phone hackers.
650-277 2413 /949-4685098 / 949-468 5084 these are the numbers that have been calling me the whole morning.
