Bad Service on claim

My parked vehicle was damaged by a driver insured by MUA. I was provided with the details of his policy and started the claiming process as the vehicle's boot was damaged in such a way that it can't close. I completed all the forms within hours after receiving the claim forms on 23 August 2018, with cctv evidence and a copy of the saps report. I waited fI am told someone would call me back. I eventually received a call from Luther Kekana on 20 September saying that they would send me option forms to complete. On Monday 24 September I received the said form, but it was not for my vehicle, it was for the vehicle of someone else on the same incident. (3 vehicles except the driver was involved) I rep**** back to Luther within a hour to say it was the wrong form, but no response. On 26 September, I called again and Shamieg told me to forward him the said form, so it can be attended to, which I did immediately. It is now 5 days later and still no feedback. I called again this morning and was told that I would get a call in 10 minutes, it is now 25 minutes, and still no call or feedback. Every time I call, I am told someone would come back to me in 10 minutes, it never happens. It is now 6 weeks after the incident which was not my fault. I only want the damage to the vehicle to be repaired.
