AES/PHEAA Student Loan Complaint

AES/PHEAA Student loan department,

Non-federal student loan Dealing with my lender or servicer Having problems with customer service California

I have a $ -+ loan with AES and have tried contacting them several times via email AND phone over the last month and have not gotten a response yet. I receive the email stating that communication was initiated by me and that someone will get back to me within 24 hours, but no one ever does. I am so unsatisfied with their services and policies that with thousands of dollars in exchange, I deserve a response as soon as possible. Not to mention, I have an increase in my interest rate MONTHLY. Obviously, I am unhappy to say the least. I need answers. Thank you, - -
