poor food on Mr d platform

if there was a half a star review if would still be too much for them. I ordered 2 pizza through Mr d, the most ********** things arrived without a topping. the one pizza was like an old cracker bread with tomato over( thinly spread). 24 hours later and Mr D hasn't refunded me, instead they send me a R20 voucher, they can stick it where the sun dont shine!
