Disgusted NO service

I bought a new Nissan Almera from East Rand Mall in 2014. I have serviced it there as well. LOVE the car - unfortunately there is a problem with the left front headlamp - it's not working. We have replaced the bulbs numerous times to no avail. The headlamp itself is in some way faulty - we think it may be the connector.<br> This is a major safety issue and I have been pulled over by traffic cops who want to fine me. I called dealership 5/6 times on Friday 22nd - service advisor was always busy. Sent an email to Service Mngr - N Sirkoth on Friday at 13:52. NO response. Sent email to DP Lionel Pillay on Mon - 25th at 10:05. Got a missed call from him that afternoon around 16:30 apologizing for lack of service. I called him back yesterday morning and he said he was in a Sales meeting and would call me back. No call. I even sms'd - NO response. <br> What's worse than Zero service / interest - the DP not calling you back after complaining about it and promising he would. NO longer interested in this dealership. NIssan SA can you recommend a good one who is willing and prepared to help me sort this out?
