This is a spam phone call. A girl useed chinese to ask me changing my phone plane. I said no. And then, she started to call me in the next couple days. They started to call me at 1:00AM, and 1:30 AM and 2:00AM! everytime, as soon as I picked up the phone, they hung up.
they called and left no message. I used caller id and called back and the lady said she could't speak English and asked if I could speak Chinese. I said no, and she said sorry wrong number. Apparently they are telemarketing to Chinese speaking folks.
