Bad service provider

Hi, I am pleased with the service I have received from Outsurance, but very disappointed with the service provider, SMG Durban. My claim was lodged in Feb, after waiting a while for the parts to arrive, my door was replaced and sprayed, I noticed upon receipt of the vehicle that this was a bad paint job. Smg took my vehicle back in to sort out, and this time it was an even worse job. Outsurance got involved and SMG eventually agreed to get me a courtesy car. After a long wait, they brought a courtesy and took my car back yesterday. I am not pleased, the vehicle is dirty, i can barely see through the windows. They have filled less than a quarter tank of fuel, disregarding that its the 3rd time i have been inconveniences and had to pay uber fees. I want my car back tomorrow please, this should not be another long, drawn out repair
