Worst support experience ever

I bought the lawnmower in late October 2021. Everything was fine for the first month, no issues. Then one morning in December the engine blew (I used it every second week to cut my lawn, 5 times in total I think). Took it in for repairs, which took more than 2 months as it is February now. They do not want to replace as the "oil was to dark and low". I get that the oil was low, because there was a massive hole in the engine and it threw oil all over my lawn. Support and the product quality are really poor. I used my dad's wolf brand lawnmower growing up, never had an issue in 10 years and this thing exploded after a month. Rather buy prodects like these from experts, that would recommend a better product
