brake problem

Oh, god please help us.okay, situattion is that I didn't drive my armada for a "whole week".When I did, the 2 back caliper were shut frozen.I took it to the dealer and still 2weeks later is in the shop.The stupid calipers are on back order.So, I called today thursday and they said maybe 2 more weeks.COME ON, it's 70 outside and I'm stuck with an 05 hyundai elantra, no air, no cd, no power, no sunroof ....... Okay, in other words what the H.LL 4 weeks to fix the brakes because nissan does not have them made yet. So, hopefully no one else has the same problem and goes thru this.
