Zero assistance from Mercedes Century City, simply pathetic.

Worst service ever. I made six calls to obtain a quote for 5L synthetic oil on 04/072024. Sadly the phone just rang at the parts department. After the four attempts I requested to speak to the dealer principal, guess what, just rang on both attempts. I eventually logged an official complaint with Mercedes customer care. They are just as pathetic. Eventually purchased the oil elsewhere. I shall not recommend doing any purchases with them. If you are desperate, I ask for Lance only. Sadly Lance was on leave when I called.They don't even deserve a one star rating. There should be an option for zero.
