I have had many missed calls from numbers I have no connection to. I don't answer random calls. Unless there is a letter, email or text from who ever the caller is and only if I have had some kind of dealing with them presently or past. Other random weekly calls have been from, Bolton, Birmingham, London, Brentwood, Edinburgh, Cannock, Glossop, all seemingly from the U.K. I have no debt/mortgage,/credit cards, no subscriptions, no outstanding/missed payments for anything, no car payments. So no reason to even answer these calls.
