The number 888-383-4313 is for a tech support refund scammer. They robocalled me and their recorded message gave 888-383-4313 as the number to call them for help. They are going out of business, so they want to refund the money that you supposedly paid to them for their computer tech support services. If you insist that you want to continue your services with them, and that you want to pay them, then they will insist on payment by gift card code, or Western Union, or PayPal. It’s pretty easy to keep them occupied on your Virtual Machine for an hour or so…
