I received this robo call from 888-943-9173:
This is an emergency call from your tech support company do not hang up the call you have paid for your computer technical support a few days ago we are calling to refund your money as the company has been ordered to close down press one to get the refund Press 2 if you have received the refund from us already press 3 if you don’t have any customer support subscription press 4 if you want to be added to the D.N.C. list press one to get the refund…
I called and Indain scammer "John Edwards" wanted to "refund me $400". He gave an alternate number: 206-278-6394
