Failure to refund my Savings

I have terminated from the scheme in October last year and i have passed the 4 months waiting period. I have made follow ups and i have been given different answers everytime i call. The last update i received when i called was that my savings refund is with Finance for approval, and that was almost a month ago. They always give me different vague answers. Below is the list of my call references. RFS20299 RFS***8 RFS26642 RFS29287
