Call back gets loooong time ringing then a BADLY recorded message.  Very difficult to understand but something about "...showcasing...on the web."  Sounds like some telemarketing scheme.

A number search does show this number under Windows Care / Windows PC Care with a website here http://horizentech.com/ It doesn't give more than an email address windows pc care dot com for contact

The website you mentioned:

Domain was created on 4/23/2015                About a year ago
Domain expires on 4/23/2016                        Next month

Do you REALLY want to trust a website that was intended to last only a year?

Registrant City: Hyderabad
Registrant Country: INDIA

Hmmm..
Does not look like local service to me ... looks a LOT like an overseas scammer that wants to "fix" computers by sucking them dry of money-making information.

He made my website for groceries store and there was never problem with the guy..

Sure he did---NOT!!                SHILL ALERT!
