I got a call from this number, picked up, said hello, but there was no sound on the other end. After 19 seconds, the call went dead. I called it back; after a few times of it being busy, it finally rang. When they finally picked up the phone, they never said ANYTHING!
I received two calls from this number both I missed with no message left. After the second time I called it back, it lasted a whole 11 seconds and was disconnected. Who is this?
