Refund not paid

Good day, I was under debt review with debtbusters, they were excellent with payments and sending me statements. I received my clearance certificate in December and an email from direct axis stating that i had a refund due to me. Debt busters had assisted me with sending them the necessary paper work sent to them. Direct axis advised that payment was made to debt busters on the 27th of January. I have called and emailed on numerous occasions, they take forever to come back to me. I spoke to a consultant yesterday who said that she would contact hyphen PDA as the funds are with them. Today is the 12th and I have still not received my refund. I am quiet disappointed as I held debtbusters in great esteem and towards the end this is the service I receive.
