Unpleasant service

Struggling since July 2022 to get a third party claim processed Agent complicates matters constantly by requiring documents to be resubmitted as constantly there is stuff outstanding,inefficient service and unwillingness to assist as I'm an external client.No follow ups done as I must make constant contact to get updates on matter.Its ridiculous service and he definitely doesn't know what service is or how to treat clients irrespective of who they are.
