BP voucher on Vodapay is a ****!!!

Bought a BP voucher for petrol, what a waste, went to 4 different BP garages. 1. We dont accept the voucher, must go to BP express 2. BP Express - we cant do it as we have loadshedding 3. BP Express - we do not have the machine to process the voucher (after 30min of finding the manager) 4. Checked if the voucher worked, it worked but when they filled my car, the filled R313.94 when my value was R440.

Manager took my details down and admitted that BP and Vodapay are not aligned and that I'm not the only customer, its now 8 days later and no feedback what so ever
