Blocked calls and vouchers taking long to get them

I ordered 2x R150 Burger king coupons plus a pnp monster coupon on the vodapay app on Thursday. I still haven't received my vouchers. Your consultant told me that you had a glitch what what. Other people are ordering their vouchers and receiving them few minutes later after buying. Mind you it's not the first time this occurs to me. What breaks my heart is that am a loyal vodacom customer for 12 years now and am thinking otherwise. You also blocked my calls to call customer care. I was told to wait for 72 hours. And what's sad it's that I really needed those coupons because I used my own vodabucks which are hard to raise.
