Who called from 2010201023

Called just now / 9:10 at night.  Demanded that I get in front of my computer that I had a windows operating system that has been getting hacked.    He would help me stop it.

Well this number just called for tenth time today...it's 1130pm lucky I didn't make it to the phone in time..ohhhww I'm pissed

called at 8 AM. Didn't answer. No message.ID 'Name Unavailabl'

Received a call from 201-020-1023 at 11:40 PM...no one was on the line and it woke both my husband and I up.

Received a call at 7:35 am but did not answer as I thought it was fishy. Anybody who needs to call me that early is calling me on cell or home # not this second line I use for business. I also had 2 calls that said Private, 1 before and 1 after call from 201 #. May have been same company or scammer.
