18 Months Excess Recovery

I am still waiting for feedback regarding my excess recovery for an accident that took place on 30 March 2019. Almost 18 MONTHS ago. When I call your call center to get an update they tell me they are still awaiting details of the registration of the other vehicles. Details which I submitted to you almost a A YEAR AGO. Further, there is also a case file and number opened which contains ALL THE DETAILS you are looking for yet you are too *********** to do anything about it. I am at my wits end and absolutely appalled by your gross incompetence. I shall be getting the short term insurance ombudsman involved among seeking other advice. It has almost been 18 months, to recover excess. PATHETIC.
