PATHETIC SERVICE FROM NISSAN SOUTH AFRICA!!!

I have bought an air conditioner low pressure hose from the Nissan Dealer in George and it failed within the warranty period. I bought another one submitted the faulty part for a parts claim just to be told that I cannot submit a parts claim as procedure was not followed. As the Consumer, I was never informed of any Warranty processes, neither are these terms printed on the purchase invoice. Since I received NO assistance from the local Dealer's Service Manager I escalated my parts claim issue in writing to the MD's office of Nissan South Africa on 30 May 2024. I keep receiving the same communication but my issue does not get resolved. I think this is pathetic service from Nissan South Africa not to be able to resolve my issue or have a final outcome in more than 1.5 months since my complaint.
