Santam claims card faulty

Last week I have received a claims card upon finalising a claim with Santam. The assessor was very helpful, but indicated that they do not make cash payments. Upon receiving the card, I asked for it to be activated - upon which no response was received. Should I have assumed that it is not activated? I went to start replacing the items at Game - the card was declined due to insufficient funds. Again it happened when I attempted to buy a cup of coffee. I then went to an alternative supplier - no change. Still declined due to insufficient funds. This embarrassment in a shop is unacceptable. I have made it very clear that I will have to start replacing the laptop urgently as I need it for my work. Seemingly no sense of understanding. Why change a system that worked to something that ridicules a claimant? I need urgent attention to this matter as it is clear that this card does not work as was indicated by the assessor.
