<prompt> Human: So my car BMW 328i 2011 is still having the coolant leak once I drove back from the shop and checked it the next morning.The dealer charged me 300 to fix a split hose that was supposed to the cause of the leak, but clearly that wasnt the case. Im going to try to take it back and have him correct it, but what if he raises another issue which he didnt diagnose or another thing that needs to be taken care of? What are my options with this one? I paid with a credit card.Thanks!  <response>: Id first see what the mechanic says before I go on the war path.
