Bad Customer Service

I bought the mazda cx3 in January at Mazda Midrand assisted by Sello A month after I got the car the mirrors and the windows where not working and the passenger seat cover was out I had to go back to Mazda for them to fix them for me and they sad they will call me to come back and fix the passenger seat as they have to order some "parts " for the seat till today no one contacted me I gave them sales of a brand new car and the consultant promised me that I will get something like a thank you gift of R1600 within 2 weeks and I got R1000 after a month after calling them 100 times to remind It seems like after they got sales they dont care about the customer
