Delay in payment

I would like to express my disappointment with King Price. I have been sent from pillar to post in resolving a claim for 5 weeks now. I have comp**** with every requirement on my side and everytime I speak to a consultant its like I'm starting all over again, asking for the same documents I have already submitted. For example they are still saying they are going to send a courier to fetch documents, but the courier has already been dispatched to my residence to fetch the very documents they want. The courier company has confirmed delivery to King Price with even a name for who signed for it.

The documents have also been shared via email with my consultant there and she has acknowledged receiving them, hence the claim being approved but when it comes to payment they essentially want to restart the process.
