VodaBucks Store coupons issues

VodaBucks BP coupons is a sham, visited 4 different BP service stations where i was told that they do not take coupons and are not aware of the relationship and new processes as their machines are not equipped to take coupons. I then decided to log an enquiry with Vodacom and was posted from one call centre to the other, with minimal assistance. From BP side of things, the Supervisor from Sinoville fuel station told me that we is willing to deal with coupons at that moment, i should get their head office and Vodacom to send him an email and come back the next morning, what a service....
