Bought 150 Vodabucks worth R49.90 but only R4.99 deducted at Milky Lane

Vodacom Vodabucks is misleading as I bought 6 Milky Lane vouchers that was showing that it is for Caramel Popcorn waffle worth R49.90. To our rude awakening, the voucher was only worth R4.99. On the Vodabucks app under vodabucks store it stated that "When redeeming a coupon in store, the full voucher amount will be deducted from the final transaction" It does not mention that the 150 vodabucks voucher is for a R4.99 discount. If I'd known that I would not have purchased 6 vouchers to treat my kids at Milky Lane. Imagine the embarrassment of being notified that your voucher is only deducted R4.99 but on the Vodabucks vouchers it shows R49.90. I want my vodabucks reimbursed because the vouchers was misleading and not correct and I wasted 900 vodabucks. This is not acceptable. To my surprise the Milky Lane vouchers is removed from Vodabucks online store. Why is it removed. On twitter I am not being helped as I am being asked questions but no resolution. I provided the cell numbers from where the vodabucks vouchers were purchased from. That information should be enough as you are not required to give ID numbers when using the Vodapay app. Why all the questions. I want my refund of vodabucks vouchers. I never had any issues at Burger King when purchasing and buying with Vodabucks vouchers. The cell numbers is *** and ***. Vodacom has access to view what vodabucks vouchers were purchased and for how much.
