Frustrating service consultants

I must say, I am very disappointed in the recent service I've received from Renew It. I had my car repaired by them in December and wasn't happy with the work done. So since it was festive, I had arranged to come in later in January to get the issues fixed. I have BEEN calling them to try and arrange when I can come in but ist been excuses and endless promises of them saying they will call back but not even once have they tried that.

Now, the lady that I used to communicate with resigned, so I got referred to a new lady Anna-Marie who does not follow up and clearly doesn't care that this is a December issue and it's now March.

I am so frustrated because people really don't value customer service, even a phone call puts one at ease sometimes.
