Bad customer Service and Refusing to give me spare keys for my Car

I have received bad service from the Hyundai Boksburg Branch from the Manager and a car dealer Named Thabani...I bought a Grand i10 in 2017 and I wasn't given any spare key for the car...They promised to make a key for me and I went back about 5 times requesting for the key but till today I haven't gotten my key. Today I sent my mom to go ask them for the key and when Thabani saw her he ran away because he knew she was going to ask out the key. I feel very frustrated because I had to call locksmith two times because my main keys were locked in the 2times. They don't care about their customers and I regret ever buying a car from them.
