Who called from 7815031820

My understanding is that that is the technical support number for kaspresky internet security software - not sure why they would call you.

I called them by error because I thought that they are the technical support number for kaspresky as they announced, but they were not.
they pretend that

This number is the number that Kaspersky has on their paperwork, their website and on your Kasper App for Support.  I called them due to an issue with Kasper on my device and they were able to help greatly.  Did not ask to "ghost in" and control my device - this is a SAFE Number to call.    ADVISEMENT: a LOT of the techs will speak with an "India" Accent - this is normal, this is also the number that will call you to do a post-assistance call for a survey on how the tech that assisted you did.

I received a call from this number and was charged $12 long distance charges.  I did not call this number, I call their 1-877-665-4717 number.  Please explain
