Complaint about Nissan Springs

I bought a used vehicle from Suhail Chotia in March, he never gave me a spare key and service books for the vehicle, he **** and said the books and keys are kept at their head office, and promised to update me, he never did, everytime I followed up with him he will give me a different story. Then I escalated to Nissan Head office in June, thats when he paid for the spare keys to be programmed by land rover nelspruit. When I went to get the spare keys from nelspruit only to find that the computer box is not compatible, then lad rover nelspruit sent Nissan Springs that they needed to pay for the computer box, theu never responded for almost 2 months, until I followed up with Land Rover neslpruit, thats when they told me that Nissan Springs has never responded to any of their emails. Then last week when I called him, he told me it's not his problem and tried to shift the responsibility to Land Rover Nelspruit, and Land Rover was only trying to assist me as a customer. When I explained to him that I shouldn't even be talking to Land Rover but he still kept on shifting the responsibility to Land Rover. I am really frustrated because I feel that I was treated u fair by Nisaan Springs and they are not even willing to take responsibility. Now I have a car that doesn't even have a spare. At 1 point when I was following up with him, he was very arrogant and told me that its not like a need the spare key, I must understand that he's doing his best. I felt very disrespected as a customer I felt that his response was not appropriate. 5 months later I still don't have my spare key. I feel like I bought the car from a backdoor dealer. Now Nissan Springs in bringing Land Rover ls brand down with their disregard for customer service. I am very frustrated.
