Unacceptable customer service experience.

I took my car to GWM Boksburg for a diagnostic. On the 23 January 2026, I was informed that there are parts they need to order. I paid a 50% deposit, and was informed that order takes about 5days. I have been trying to follow up on this job! When I picked up the car on 23 January 2026, I was assisted by Palesa at reception.I have spoken to Palesa a few times after that date.She always promises to give me an update.Today, 02 March 2026, I was put to parts, and held on forever.This is costing me money.Can someone tell me what the problem is here?
