TL;DR I noticed some fraudulent activity on my PayPal account and it was sorted overnight
Last night I received four emails from PayPal regarding purchases from Google totalling around $8 altogether. Now, I’ve never bought anything from Google, ever. So i initially thought that these were fake or phishing emails. I logged onto PayPal from a different device, and saw that those payments had indeed been taken, and that Google had been set up as a pre-authorised merchant a few days previously.
I raised them as unauthorised with PayPal straight away, and they immediately forced a password change. They said that they should get back to me before 23 April.
This morning I received an email saying that the transactions were found to be fraudulent, and the cash had been restored to my account.
So well done on swift action by PayPal!
