BAD CUSTOMER SERVICE

I have been trying for the last 3 months to change my address on my policy. I cant understand how the lady managed to get the change of banking but not the address. I have phoned almost every week to try resolve this matter still nothing i was even promised by the manager on Friday the 27/11/2020 that he will have an answer by 11 am still nothing it's the 01/12/20120 when i called this morning i was told he is in a meeting he will get back to me. Who pays for all the airtime Ive been using phoning week in week out trying to resolve this matter ? Yet if you miss a premium you wont be covered. Who do i speak ? How do i resolve this matter ?
