AES/PHEAA Student Loan Complaint

AES/PHEAA Student loan department,

Non-federal student loan Dealing with my lender or servicer Trouble with how payments are handled California

My loan servicer AES Success, has processed double payments without my knowledge. I have contacted their customer service only to be led in circles even when asking for a supervisor, a rep literally told me " No one is available '' when I asked for her supervisor. When I inquired further she said " They are all in meetings '' I was willing to wait or leave a voicemail on their phone however the rep told me I could n't wait because " I ca n't tell you how long they will be in meetings and you can not leave a voicemail on their phone. '' I then asked for their extension so I could call myself and the rep said " I ca n't give you that information. '' I have never had such an issue trying to talk to someone 's supervisor, and to top it off, the rep had an attitude about it making it seem like I was asking for the world, and she talked down to me when I asked her if she had my information correct. Terrible customer service. I was unable to get any answers regarding the double payment they took out of my bank account and my only option was to put in a request for her supervisor to call me back ( which could take up to 24hours ). I am not holding my breath on that.
