Lifetime warranty worthless

Good day<br> <br> I reported that the paint from a previous repair is starting to bubble and fall off with certain places where the undercoat is visible. The grill was replaced but the bracket holding the inter cooler in place was not installed causing the grill *****s to punch 2 holes into the inter cooler. I reported this the first week of January 2016 and I am still waiting for the vehicle to be accessed. It is now 3 months later and every time I phone to follow up I get the same excuses namely that they cannot get hold of the assessor but the assessor will be in touch with me soon.<br> <br> What is the next step? may I please get my co-payment and premiums back as it seems that Auto & general is incapable of repairing vehicles. I already cancelled my policy due to this poor service.
