What is your question?
AC stopped coling, so I tried adding coolant, but it will not take it. What could be the problem? I've replaced the compressor three times in the last two years....agh!!!!!!!!!!!!!!

Do you mean you added refrigerant to the A/C system, or coolant into the engine? If may not be a lack of refrigerant, there may be something else wrong with the A/C system. You may have overcharged the A/C if you've added refrigerant unnecessarily, and engine coolant has nothing to do with the A/C system. You need to get a qualified professional to diagnose your A/C system. go to a MBZ specialist and get him to check it for you. If you want to find a specialist, here's our directory link for you: https://repairpal.com/mercedes-benz-repair-in-westminster-south-carolina My experience with used or rebuilt A/C compressors has been unpleasant and I would not like to use a rebuilt compressor in my work. Also, if the compressor has failed, it's usually necessary to replace the accumulator and expansion valve because of the debris that a failing compressor generates.
