New one for me. WIFI call. I don’t answer calls from unknown numbers, let alone WIFI calls which I know very little about. I’ll ring it midnight tonight and see who answers, or company message left, done that before and comes up with can’t connect check number, or company message with open/closing times. My new phone is great, scam/spam calls come up red with a notification it’s a suspected spam. If they they are not courteous enough to leave a message, then they obviously really don't have any bumpiness contacting me!
