UNAUTHORIZED SUBSCRIPTION

THERE IS AN UNAUTHORIZED DISNEY + MOBILE LOADED ON MY CELLPHONE NUMBER. I HAVE MADE NUMEROUS CALLS SINCE DECEMBER TO HAVE IT REMOVE. HOWEVER IT KEEPS RENEWING. MTN *123# SHOW NO SUBSCRIPTION BUT MY DISNEY+ SHOWS MTN MOBILE PLAN. I WANT IT REMOVED AS I DID NOT AUTHORIZE IT. I ALREADY MY OWN DISNEY+ PLAN WHICH IS NOW BLOCKED BY MTN
