Very Poor Parts Quality

Very Disappointed with the quality of parts supp**** by MPD. 24-03-2022 we bought parts from them to do a complete engine overhaul on a Cherry Tiggo. Within 3000km's the water pump failed, broke the Cambelt and bent valves. We contacted MPD Cape Town regarding the water pump bearing that failed with all the video's and photos as evidence. We were told to return the damaged parts and wait 2 weeks for the report. After numerus mails where we told them we can't wait that long and leaving our customer stranded, they finally gave us a new water pump and cambelt after a week. Installed the new pump and discovered that the new pump has a problem too, the pulley is wobbling very badly where the cambelt runs on.. Sent videos to MPD again and returned the 2nd pump. We then fitted a Masterparts water pump that does not wobble and works perfectly. After resolving the issue with the water pump, we unfortunately had to remove the cylinder head because of bent valves. After 3 weeks we received the report from their supplier stating that we overtightened the cambelt tensioner that caused the water pump to fail. Fortunately we're a 5 Star RMI workshop with 3 qualified Mechanics and 1 Master Technician. ( Note That Our Master technician is the only one allowed to do engine Re-builds. ) We will not accept this poor judgement from their supplier to go around and judge us for this fault, we have all the proof of both water pumps used and new that's defective. MPD also refuses to supply us with their supplier details so that we can contact this special Judge on how we do work. At the end they only supp**** us with a cambelt and refunded us on the defective water pump. We had to pay for the R7392.51 bill because of the poor quality parts supp**** by them. I WILL NOT RECOMEND ANY ONE TO BUY PARTS FROM THEM.
