Just had Microsoft on the line

Just had a Microsoft techie on the line (my landline) and let him onto my VM through a VPN. Unfortunately I am not as good as you guys, however after telling me of the £5 charge of a new product ID (hackers broke my old one) they tried to get me to fill in a credit card form. From this I have the address of where it was going to:

cermaktech.com

which is an obvious tech support scam website. (link to whois: Whois cermaktech.com )

The false phone number used in obvious bullshit number ( 0016952371…) so thats no use to Bob.

However the one on the site is 1-888-423-7625

Just tried and I got a company called syrmatech.com, which seems legitimate, I am guessing that the scammers stole that too. Now how do I remove the number from BOB please?
