[2019] Is there really no customer support email??

I thought it was a meme that social media is primarily customer support, but i tried to find one and can't see a contact email/number. I don't use reddit but i received an email from an official Jagex email account ([email protected]) that my email for an account had been changed. I have multiple accounts tied to that email address and couldn't seem to find out which one, if any, has been changed. Is there any way i can contact anyone about this other than asking on reddit/twitter? I'm using my work laptop just to be safe btw, even though i scanned my computer already and there was no issues.
