Direct axis worst customer service ever

I have settled my loan account with direct axis and had paid a little extra as well as had a credit on my the account. I am emailing as well as calling on numerous times to get the funds refunded to my account but the company does not respond to my emails as well as when I get through to their call center team they always say please hold then immediately end the call. I am calling from overseas and I am wasting loads of airtime trying to resolve this. This is not fair and is very frustrating. my loan account number is as follows: ***. There service is very poor and wont recommend anyone using their services.
