Terrible inferior products from Ryobi pathetic aftersales

Good day to all Once again I am having problems with the ryobi 50l compressor purchased brand new on 27/09/2020 not even 3 months old and the unit keeps running all the time with no pressure build up. This is the 4th time we are using this unit for simple DIY usage around the house. I take the unit back to Ryobi only to be told that it is a 7 - 14 working day period just to have a look at the product let alone fix yet it is still under warranty. This I cannot understand as this failure is not our fault but the products inferior quality. I had same problems with a 900 watt 115mm semi professional angle grinder which we used twice only to have the front bearing fail. In short I would never recommend Ryobi products as the service and repairs aftersales is appalling. Do not be fooled by the cheap price and marked down specials rather invest in a product that is more expensive but built to last. Ryobi I await your speedy response to resolve this matter as soon as possible.
