economy lube transmission pan bolts broken mississauga Ontario Canada

I had went to economy lube just for an oil change but then ended up that i need to flush my raditor and change my tranmission fluid. in which i did. After the service was done the next day I noticed red fluid on the ground which was the transmission fluid. went back and they checked it out re silconed it.  left and the next day saw the same thing again on my driveway. took it back to them and the sent to another mechanic.

The mechanic their told me that they snapped about 6 six bolts.  So i spent 5 hours with this mechanic as he tried to make new holes to put in new bolts. It seemed ok for few months but now its leaking again. I took it to an actua mechanic i trust and he told me that the mechanic who tried to fix this used unproper bolts. Now i dont now what to do. I need this car. Can you help me
