Extremely disappointed with Miway

Unacceptable service received from Miway. I'm even more disappointed as I usually receive great service from Miway, I was definately not expecting such sub standars service this time around. My car went in for an assessment and repairs at a Miway panel beater , 3 weeks ago, going on 4 weeks. The panel beater keeps on moving the ETA date, everytime I call. No courtesy from panel beater or Miway to even give me a call to provide status of repairs. I've escalated this matter to Miway numerous times, to date I still don't have an ETA. I urgently need my car to be fixed and released. Miway, please be responsive and assist urgently.
