Total scam. Called Apple Support over problems with my wife's IPAD and was connected with Click4Support in India somehow. They told us that our computers IP address had been attacked by outside hackers and that they would remove all threats for $ 499. They then told us we should probably get their "Platinum" protection plan for another $ 900 or that we should probably buy another IMAC for $ 2000. Bottom line - we got charged $ 1400 for something that turns out could have been fixed for around $ 50. I now have to take both our IMAC and IPADS and have everything they put on our devices and have them removed.
Whatever you do - stay away from this company! A total scam
