Who called from 2676033984

The caller did not leave a message.

Have gotten 2 calls a day from this number for the past 3 days. No message left, when trying to call back it rings but then gets disconnected or goes to a busy signal.

Did you purchase any software over the Internet in the last week per chance?

I'm getting calls from this number, and I purchased software over the internet. Does it relate to this?

It could-especially if your purchased the software from a questionable source. Did you allow someone to remotely access your PC to install the software?
