Liberty life

After paying a policy for 35 years , it’s taken Liberty 2 weeks to inform us that they didn’t receive all the attachments to an email for my Late Husband’s Death Claim - and are asking for a ‘cancelled Cheque’ to confirm beneficiary bank details . Perhaps they haven’t heard we stopped using Cheque’s in SA nearly 2 years ago ! I am worried what my beneficiaries will have to go through when I die and they try to claim from my policies . I am an ex Liberty staff member so not impressed, we used to pride ourselves on good service. Momentum paid out days ago!
