So I’ve not got a recent popup for either of these 2 people, but they are still answering their phones. UK numbers:
08000868671 and 08000465264. The latter number belongs to scammers who call themselves Webexllc.com or fastsupportonline.net (the latter domain is registered by someone with a Mumbai address). Happy spamming.
Seems 08000868671 is now being answered by UK Cyber Experts Limited with a Birmingham Address Companies House: https://beta.companieshouse.gov.uk/company/11423992?fbclid=IwAR2R9Xi8HdeRc2OlLbIgW7rUMpCa5j_NYSKz4udn4uSSTquqAeKd-yzWz7Q
