Ruan Pressure Washer or under pressure services

I bought a pressure washer machine from these guys on facebook, i called and we met, i payed R700 for the second hand machine only to find out that its not working when i got home. i then called the seller who's Ruan and he never picked up i called several times with no success, i then went to his place of work where we did a transaction to return the machine, I was then told to pick it up within 2 days of which i went and never got the machine, I've been going back and forth trying to get the machine with no success i then gave up and aske for my money back and never received it. this matter started on 07th of July till now. beware of the company call under pressure services or Ruan Pressure Washer operated by Ruan and his father and you will get ****med like i was.
