Camp Master

I purchased a new Camp Master 205 from Makro on 06/04/2024. After just 4 months, the paint on the lid started coming off. I contacted Camp Master, and now they want me to take the trailer back to Makro so that Makro can send it to them for assessment. The nearest Makro is 230km away. Who is going to cover my diesel cost? Also, how long is this going to take to be sorted out? I am insisting on a new lid, not one that has been repaired. I paid for a new trailer. And even the welding on the lid is poor.
