Vodacom Pay Once Prepaid Data bundles

Pay once prepaid data bundles do not follow terms and conditions. As per terms and conditions:<br> \12. Pay Once data bundles are valid up to 24:00 on the 60th day from and including the day of purchase".<br> This is not the case. I have purchased a 2gb bundle however the data that should be available till 60 days is not available once the next months bundle is received. I have had this problem for 2 months now. Tried calling Vodacom to resolve but have had received no feedback to date. Service request reference number A6-XA0K-YJ32O. This was logged around the 27/28th August. Seems like Vodacom does not understand the definition of customer service"
