Hydraulic Cylinder repair shop

Spent R11,000 on the 'repair' of an hydraulic cylinder. It failed in under an hour. Sent it back on two occasions; both times the cylinder buckled within minutes. When a refund was requested they denied. Not only is the workmanship of this shop BAD they also DO NOT guarantee their work, contrary to what they claim on their website. THESE PEOPLE ARE ******! THESE PEOPLE ARE ******!!
