Dishonest and lazy staff

I took my car to automagic Rivonia on Monday the 23rd. I was told I would get my car back in 3-5 working days. We had a family emergency on Monday evening. I called automagic and spoke with Nadine. I explained the circumstances and she assured me the car would be ready by Friday for the latest. We received an automated sms saying that the car will only be ready on the 6th of April. When I called to query Nadine said it was a glitch in the system and to ignore the said sms. Which she is now denying. Everytime I called and spoke with Francois, he either forgot or just didn't bother calling me back. They have total disregard for their clients. I'm shocked as to how Nadine can deny an entire conversation she's had with me. I'm appalled!
