Terrible Service (Still not sorted)

I wrote a complaint about my insurance claim last week about my claim from 22 March 2016 that has not been approved and when it was approved it was done half. Not all the parts were on the quote ect. The assessor Dave phoned me to make an appointment to come and re-asses my vehicle. He assessed my vehicle and assured me that everything will be sorted and he will send me an email on Friday. He was very friendly and assessed my vehicle thoroughly. I only got a phone call yesterday (Tuesday) saying that there are some problems occurring. Can you please sort out my claim. I hate to go to this extent but I'm really miserable I cannot phone Renasa directly they informed me that they only speak to brokers.
