Terrible and annoying

my gran is deceased while having a policy with them in June, we went to claim, they took their to process the claim as they kept on asking one document that is short, when we give them that document they will ask for another document, they even want documents that will FICA a minor, even at their branches they are so slow as they are advantage of mourners, what annoyed me more is that comes July and August they deducted their instalments however the deceased was already laid to rest, worse the funeral policy from them already paid, but the deduction only them idiots know, they #WIN at our expense.
