Air conditioning not working

The air conditioning in my car stopped working recently. I assumed that it just needed recharging and so took it to ATS who recharged it. At first it seemed like this had worked, however after less than a week the AC stopped working again. At almost the same time as the AC stopped working, the compressor seized and the power steering belt snapped. I am not sure how these things are related but it seems like a big coincidence if they are not. Has anyone heard of anything like this happening before, or have any idea what could be the problem with the AC?
