Poor service from Direct Axis

I had an account and on the 7 Sept 23 i settled the whole account.Unfortunatelly the installment for Sept month also went off.The call centre confirmed that i had a credit with them and will be refunded.Up till today ive been phoning everyday to sort out my refund but get the same answer that a manager will contact me.No answer or indication of what happened to my refund.Very poor service and even after i sent email there is no response from Direct Axis
