Facetime hack?

Hi all,

I really hope I’ve come to the right place.. apologies if not, honestly no idea where to take this query!

My mum got in touch to ask what was going on because she got a late night facetime call from ‘me’. Apparently there was a woman speaking Polish (possibly) and when my mum realised it wasn’t me, she hung up. I was definitely home alone when the call was placed, and my laptop (the only device I have facetime on) was not in use.

Two days later, I received an email from TikTok asking me to complete an account sign-up I hadn’t started. I only mention this because this email address is also associated with facetime.

Not sure what’s going on here and what I should do next.. does anyone have any tips?

Thanks in advance
