long processing and bad customer service

Renew it has been fixing my car for over a month now. Initially I was kept up to date with the progress and would track it on-line and get feedback from the person responsible for my case. Then it all stopped. I called them twice and both times they told me there was someone specific that could help me and the person will call me back, I never got any call backs. Then to make it worse the guy giving me updates nolonger works for the company and I wasnt notified so was sending emails to a non existent email address . Also, just the length it has taken for the car to be fixed, clearly shows no urgency being demonstrated to assist thr customrr quickly.
