Audi Century City- HORRIBLE customer service

I made contact with Audi Century City on 11 December 2024. Spoke to Caleb, who assisted me well and expeditiously. He ordered parts from the factory to be delivered in 3-5 working days. The following day, 12 December 2024, I made payment at the branch, where Mario advised that they'll make contact with me when the parts have arrived and that they'll give me the quote for the labour. I contacted part department a week ago and was told that Mario is busy and would call me back, which never happened. I called again on Wednesday 08 January 2025 and was told Mario is on leave and that someone would call me regarding the quote for the labour. Now, 10 January 2025, I am still waiting on a call from Audi Century City. I called them today, Cindy put me through to Madeleine; I hold on and the call gets dropped. I call back again, Cindy advises me that Madeleine is on another call. I leave my number again; as I've done over the past 2 weeks; hoping that I'd get a call back from them. Absolutely Horrible service!! I've been dealing with Audi dealersips for many years and this is by far the most disgusting customer service I've ever experienced!
