Ryobi 50lt compressor problems

I've have purchased a RYOBI 50LT COMPRESSOR. From day 1 I had issues, as I opened the the box it was covered in oil, was then told there's no stock and had to wait for Ryobi to be open as this was December, this machine does not build pressure, it already been to ryobi twice, and it still has the same problem, I am very unsatisfied with this product, everytime I have to use it, it just don't work, I am tired of going up and down to return this machine, takes 3 to 4 weeks to come back just to do the same thing. Unsatisfied customer ☹️☹️☹️
