Terrible service from VW Hatfield Braamfontein - Again!

I bought a brand new polo 1.2 tsi from Hatfield Volkswagen Braamfontein in March 2017. I was assisted by Dale Williams. On 21 August 2017 the car had a shuddering on the clutch and the light for a airbag error came on. I phoned Dale on 22 August to let him know about the problem. He responded via email on 23 August. Said it could be battery problems. I told him I drive the car daily and the battery was 5 months old so how could it be? He didn't get back to me after that. On 28 August i phoned VW breakdown services and the car was taken to VW Barons Postmasburg. Car was there for 2 weeks standing in the sun the whole day and they could not find the problem so they just reset the error. 3 weeks later the error light came on again - the second time and still before the first service. Phoned Dale again he said he will talk to his workshop manager- still waiting for him to call me back. Took the car for 1st service on 10 October at Southey VW in Kimberley and they could also not see why the error keeps coming on. Also just reset it. I am very unhappy with the poor service i got from Hatfield Volkswagen Braamfontein as this was a brand new car i bought. Now I have to put my life in danger as i don't know if the airbags will pop if in an accident. Very unhappy client.
