What ACS failed to tell or explain to you is that they NEVER garnish...they are a lender/servicer and that is NOT their job. When you make less than the required payment, you will be past due. After 9 months of past due, ACS will default you back to your guarantor. Your guarantor will pay ACS off in full. At that point your loan becomes due in full per the default clause in your contract. You will be placed into collections and up to 25% in collection fees be added to your account. This is the point that tax offsets and wage garnishments occur.
Your attorney has his head in a hole or is pulling information out of thin air. Administative wage garnishment is HUGE. He has given you horrible advise based on his experience or opinion which it totally not fact. Wonder if he ever had a student loan...
