No after sales customer care

I recently purchased a car at North cliff Suzuki and i have had endless problems with them. Firstly it took them over 5 days for me to get delivery of the vehicle because of the chip on the windscreen i had to use public transport and they did not care just to even follow up and let me know when i can get the car. I was the one after them. Now the permit on the car has expired for the second time and i am back to taxis again. I have sent e-mails to the dealer Principal and he reads and doesn't even have a decency of coming back to me. I am now using taxis for the 3 time since i have purchased this car. The other issue is that when i initially bought the car i asked about the spare key and the guy told me he will look for it only after i have signed all the documents i am told i have to buy my own spare key...the service is shocking and terrible.
