Have had multiple calls from this number over the past several weeks. After I answer "hello?", there is no response, no sound at all but the line stays connected until I hang up. Yesterday, the caller actually came on the line. It was a woman who spoke with a heavy accent and bad English, wanting to talk to me about my home loan, quickly telling me it was not about refinancing but about a "special program" they wanted to make me aware of. She did not identify herself or her company. She talked fast and gave me no opportunity to politely refuse, so I put her on hold to take another call and when I came back she was gone. Today, two more calls from this number with nobody there. There is always a fast busy when I redial. Getting very tired of this.
