sounds like a real sh!te day
i had similar weekend doing my rear brakes as a caliper had siezed on, spent all weekend getting it all done after been given the wrong parts and having to travel all over looking for a caliper, then finding out it was the carrier that was siezed and not the actual caliper..
in the end iv ended up with new rear discs, pads, bearings, a new caliper, the other side caliper fully re hauled, new split pins and lock washers....
should last a while
