Poor and unprofessional service

Good day I took my Nissan NP200 1.5DCI for a 90 000 km service at Nissan Standerton (Penta Motor Group) on 06/06/18. since receiving my vehicle back I had to take it back 3 times to the dealer to fix the damage they cause to my vehicle. I nearly paid R10 000 for the service and did for sure not receive the quality service Nissan South Africa promises that you as customer will receive form a Nissan dealer. The so called master technician advise me that the left shock was leaking and had to be replaced. I asked the parts department to submit a claim as my vehicle is still under warranty. as usual the claim was rejected by innovation (the company who deals with the Nissan claims ) and I bought shocks out of my pocket. unfortunately the problems became more and more and I contacted Nissan South Africa who also seems to turn a blind eye to this type of poor and unprofessional service. last week I book my vehicle with a Longtom dealer to conduct a 101 inspection on my vehicle sins the problems Nissan Standerton caused to my vehicle made me uncomfortable and I feel unsafe in my own vehicle. Longtom then advise me that the front shocks seems to be fitted wrongly and advise me to take my vehicle back to Nissan Standerton. I called them out and the mechanic told me he forget to told me that the front shock mountings are not good. this is a big lie and I can't trust them with my vehicle sins we experienced such issues with my 90 000 km service. the next stop now will be the complaints commission as I have the photos and 101 report on my vehicle and Nissan South Africa is turning a blind eye.
