Appalling Service - Market Toyota Tokai

In March I decided to trade my 2020 Toyota Cross in for a cheaper car to cut cost due to rising prices of everything in South Africa. I went back to Toyota Tokai because that's the only dealership that I trust and I bought 4 cars from them already and I always received the best service ever from the 2 salesman. Unfortunately I had to deal with a completely different salesman due to the fact that my regular salesman has left the company. According to the new salesman Faheem the vehicle he had for me would have a lesser instalment and also light on fuel and I won't have any problems with the Opel Enjoy. I decided to take the car putting my trust fully on the salesman and yes the instalment was less,BUT the car was heavy on fuel. I made notes of the faults on the car and messaged Faheem knowing Om still waiting on my license plates. " I will sort it out" that was the response. Collect my plates, and asking for an update and what is he planning on doing, just to find out nothing was actioned. I kept calling, emailing requesting a different car and I was given the run around. They then phoned me to leave the car with them to have it checked out, which according to their automark guarantee you won't have any issues on the Automark cars and it's a guarantee. They kept the car for more than a week and only replaced the breaks, my fuel consumption is still rediculous because I used a quarter of my tank to drive to town and I was told the car was light on fuel... Really!!! I'm still having issues with my gears as well. I messaged Faheem to tell him the car is leaking oil " I will get back to you" ....I am still waiting!!! I'm paying a cheaper instalment, but the money saved is going back in my tank and it's not because of the fuel hike, it's because the car is heavy on fuel. Toyota Automark sales gives the wrong information to clients, it's all about making a sale and getting that commission. I've referred so many of my friends and family to you guys, but after this ordeal never again. As a salesman,you need to have product knowledge in order not to give your clients the wrong information, and clearly you have taken me for a ride and now I'll be taking you to the Ombudsman
