Stalling tactics

Good Day, Claim number ***. I was in an accident with your client in October 2014. After lengthy process, 3rd party claim was approved and your client paid the excess. I completed your payment release form and submitted to you on the 30/01/2015 and was advised payment will occur 30 days after submission. Person handling the claim went on leave shortly after. I call on the 5 Feb and was told by the consultant that it was not submitted for payment and that he will do so. I called on the 16 Feb and was told that it was not submitted and after a lengthy argument I was then told that it was in fact submitted on the 5th but the consultant failed to updates the notes and I can expect payment in 30days from the 5th. I started to see the incompetence already, so I called again a few times and have been told a different story each time. Finally I get told that they have closed the file and its with the payments department now but no one can confirm when the payment will be done! I am tired of these lies and stories. I have been very patient, 30 days have come and gone and still no sign of payment or feedback? My car needs to be repaired, sort yourselves out and pay me now!!!
