Recognised claim not being processed

I submitted 'Agreement of Loss' on 18 Jan 2021. Had made multiple calls, spoke to Krystal Kester 4x times a person named Florence and others about claim HLB*** not being processed.....was told problem with banking details. Then submitted copy of bank statement 3 weeks ago. No recognition that it was received, NO communication and no keeping of promises by those taking my call after going through painful wait when dialing ***. So fed-up
