Lose Power Steering problems of the 2009 Dodge Caravan

I 've had multiple times that this has happen mostly at slow speeds. I would be going along and hit a hole or bump of some sort and I would lose the power steering, thus the engine would be dead! lucky it was always at low speed, hate to know what would happen at a faster speed. Anyway I got a recall notice about that same time, and have been in 3 times to get it fixed but to no avail. I was in just April 2, 2015 and the dealer checked who knows what, but they told me I had to call a 800 number and talk to who ever. So I have tried to call 3 times the 1st times I was on the line for 2hrs and 20mins, the second time almost 3hrs, and the 3rd time 4hrs 25mins. . . All I get is "thank you for holding, your call is important to us, will be answered by the next available representive" and that comes on every minute with no results. I want the part fixed. What are my options if any??? the dealer tells me I have to get Chrysler to ok the fix, but how do you do that if they don't answer my calls?? thanks much.
