Loan Application still hanging - no feedback

Did my application almost a week ago and to date havent heard anything, no one called me or smsed me to tell me what is happening. When I did call I was told that they couldnt confirm my employment as the phone was not being answered - why my HR depart disputes. I have called the call centre several times, i am just left holding until i am cut off. Please can someone tell em what else must I do?
