Is Premium Techie Support scammers back?

Back in 2018, I was conned by Premium Techie Support who manage to get in excess of £400 from me

They've just contacted me, claiming that I had committed to a subscription fee of £800 per year for 10 years with a 5 years billing process, hence calling for a payment of £8000 or only £4000 if I was to cancel the subscription... Despite a threat of freezing my computer and legal prosecution if I did not pay, I told them I was not going to pay anything... I've now just found that they were reported back in 2018 & 2019 on the Apple community... So this is a warning: they are back and willing to get your money!
