Sallie Mae called me

I owed $352 for a student loan. Sallie Mae called me and they told me that I can settle it for only $180 with them. I told them that I don’t have that much until next pay check. The agent then told me that I should pay it by the end of the month or there’s no deal. I beg them to give me few more days because I’m getting paid on the 5^th. They then told me that if I can’t pay it by the end of the month they will start garnishing it from my paycheck. Sallie Mae is inconsiderate. They are not willing to help all they need is money!
