2001 Hyundai Accent 2001 Hyundai Accent A/C Problem

Hi,

I had a strange problem. My car would start squealing after I had driven it for 10 miles or so. I took it to a local MIDAS and they changed the A/C belt but the sound didn't go. I again took it back to them and they said they need to replace the whole A/C compressor with clutch which will cost $750. They said that the compressor was stretching the belt which then began squealing. I am a student and I didn't have that much money so as a temporary solution they cut the A/C cable. The squealing sound disappeared.

I am not sure if there recommendation was correct since my A/C is working well and cools the car quickly and efficiently. Was the mechanic taking me for a ride or do I need to burn $750.

Please help.
