No Use Vouchers

In December I won 2 vouchers valued to R250 in total.

The one was specific for me to use at an engen wimpy which expires tomorrow, 30 January and the other expires in 6 months.

This past Saturday, 28 January, I tried redeeming both and I was unable to do so.

This ultimately meant that I had to pay the bill in full and not only that, if the other expires tomorrow this means I've lost R100.

This is all rather disappointing. And I have sent an email to the address provided on their website but have had no response since.
