Bad Attitude and billing Account

I received incorrect statements and Eduloan took more money then they should have debited from my account. I also received extremely rude service from the call center agent! She said my ref number for the call is 127928 - she even hung up on me whilst I was speaking to her! She called back again and when I requested to speak to her manager or team leader she refused and said they in a meeting! EDuloan please investigate this matter as I will never use your services again due to poor service delivery
