Someone keeps calling from the above phone number

Same as Tim. When I picked up they hung up.

Same as Tim (above). They keep calling back every couple days, but never leave a voicemail.

Called my cell phone. The guy answered but I could not understand what he said - kind of mumbled. I asked him to repeat as I couldn't understand him and he said the same thing as the first time, but I still could not make out the words. I hung up.
