Called and left no vm....

Call to my business, butno voice message was left.

Called me and no voicemail. BLOCKED!

Called- Came in as Minneapolis, MN and left no message. I don't answer calls from numbers I do not know and when they don't leave a message, I block the number. I feel its easy to assume it must be a telemarketer calling because a reputable business would leave a message.
