Horrible Claim Experience

I launched a claim for a ****** device a month ago, sent proof of payment 6 days ago yet I'm told my P.O.P wasn't received. This is find out after I have called to enquire. It takes them more than a week to communicate anything regarding my claim, in most instances I have to call them to find out what the status of my claim is. Terrible service, poor communication, *********** work ethic.
