I got a call from this # (330) 779-8677. I am not sure what its for?

Same. I have no idea who it is.
I've gotten calls before from the states (I live in Canada) and it ends up being some kind of scam.

I didnt answer and they didn't leave a message so I'm guessing a telemarketer

This is a telemarketer for teaching real estate. if you want to make millions $$$$ in real estate go ahead and call back. they can get you to make one million USD ($1,000,000.oo) IF you spend TWO MILLION USD.($2,000,000.oo) with them. ;-)

I talked with Verizon & had a good experience. Then about 15 minutes later, I got a call from them looking for a survey to tell them what kind of service they provided. I just hung up on the Verizon robot because I did not want to waste my time.

Then within 2 minutes I got a call from 330-779-8677 which is a scammer trying to make me money. On my cell phone I almost never get telemarketer calls. I do not believe that this a coincidence.

The simple explanation is that the Verizon robot caller got "mad" at me hanging up and within a few seconds told his telemarketing scammer robot from 330-779-8677 to call me. Humans can not transfer data fast enough to explain this.
