I consoldated with AES and I advise strongly against them! They screwed up my consolidation horribly. I actually found out today that when they dispursed my funds to "pay off" the loans with my original lender, they accidentally sent the wrong amount. Thus, the orginal lender sent me a bill that said I was delinquent by 20 days. Apparently, your original lender must be paid in full by the consolidation loan people or they return the money to the consolidation people and request that the correct amount be sent. My consolidation was supposedly completed in November,so I already had that loan placed in an Economic hardship deferment for residency. So all along I have been accruing interest on my original loan AND the new consolidated loan which never paid off the original! Anyways, they are fixing everything supposedly and apologized for the mistake, but I am sure that somehow I will eventually get stuck paying off more interest caused by this mistake just because they are incompetent. So anyways, be careful who you choose and make sure that they actually pay off your orginal loans correctly.
