Generator

I bought a generator from Addendorff Johannesburg in 2020. Shortly thereafter it started to badly leak petrol onto the air filter. It would automatically switch off the generator. I have taken it to Addendorff Roodepoort several times. They are unable to fix it. They merely said I couldn't not operate it. How convenient. It's very unfortunate.They instead told me that it just needed service. After service it continues to leak petrol. This is so frustrating. How can they be unable to fix their own mess. Unbelievable. I regret buying this generator from them. I thought they were a reputable company which has expertise.
