The Poorest Service Ever!

I took my car in for repairs on the 21st of Jan 2016. Renew-it informed me that the rapairs will be done in 4 days. I then got a courtesy car from my insurance for 13 days, which they took back on the 3rd of Feb. By then, Renew it was still not done with the rapairs. the last time they communicated with me was on the 27th of Jan when they said the car was in the painting department. When I called to ask about my car on the 3rd of Feb, Kashwin said the painter was off-sick! I feel sorry for the sick guy, but is that my problem?? I requested to talk to the manager and Kashwin said the manager will call me back. The manager never called me. When I called today, the receptionist put me through to Kaswhin, as I was still holding, the phone hung up! Can you believe it? After all the inconvience that have caused me, when I'm the only one communicating to them, they still have the audacity to hang up on me!! I called again and the receptionist said she will get the Operations Manager to call me in the next 10 minutes. Its been over an hour and I have not received that call. I must say, I have never experienced such poor service in my life! I have been using Uber since Wednesday.
