Can't contact UK support

I have an issue where my door contact senor keeps displaying "Tamper", I've completely removed and re-added and it still keeps happening. I've also checked that the battery compartment is completely closed.I've contacted Ring via Chat and they said I need to call. I've now tried calling both UK numbers (01727 26 3045 & +4408081965767) and each time I get through, get the message "press 1 for English" I press 1 and nothing happens, it just cycles through the other options and then hangs up. I've tried calling on my iPhone, my wife's Android and my work landline, same issue each time! Does anyone have an email for support?
