Terrible unprofessional service

I had brought my Rim in to be repaired at Wheel Collision on the 3rd of December 2018 , I had to get the insurance to approve the claim and the approval came in on 4th of December 2018 and the email was sent to ********** So at that point I knew that Wheel collision had gotten the authorization and I wouldn't need to convey the message. To my shock when I called on Thursday to ask how far they were with the refurbishing the rim the receptionist lady said she will call me back and she never did, then I had to drive from Centurion to Edenvale on the same day to find out what had been done, to my shock no work had been done and I was told that they had been waiting for an Authorization , that they had received 2 days prior. mind you this was supposed to be a days job. the lady only looked for my email while I was there and only found it after I had shown her the email that I had on my phone. They apologised and said they will have everything done by the next day ( 6th December 2018) at 13:30. I went on my lunch break at 12:30 on the 6th and I was told they were still working on my rim as someone had painted the rim silver , a rim that I brought in that was already painted black. I had to wait another 2 hours to find out that the issue was still not resolved and ended up leaving without my rim because they were taking forever to get it sorted. I have never received such poor and unprofessional service in my life and I don't think I will ever be using them in future to sort out any of my rims or Mags
