Got 2 calls from this number, said hello, and got no answer, "they" then proceded to hang up. I got a call again and assumed it was a butt dial, same story.
I get the call from them from time to time also what I do is have fun with them I press one and talk to a person when they answer I say in my Hindu style voice " Thank you for calling tech support how may I help you ?" I had the guy on the phone for ten mins you could hear in his voice he was confused. I have also heard of people blowing a whistle in the phone but next time I am in Wal-Mart I am getting one of them air horns from the boat dept. and keep that with me so next time they call I will press one and when the person answers let him have it. eventually they will stop calling,
