Vodapay vouchers are invalid

I gave the Vodapay app a try and purchased 2 Netflorist vouchers. They don't work. The vouchers are invalid. Even worse I tried calling in using the supp**** number for help and no luck the system is terrible to navigate, then we get to Tobi come now really what a waste of time. I tried getting help from this bot to zero avail. Why are making false offers and dabbling in products that don't work? Don't take out money and not supply what is paid for.
