WHY BOTHER - NETFLORIST- ****MERS!!!

I received a delivery from Netflorist attached with the card at the back of the it states “Here’s a R150 Netflorist voucher …. with the voucher #. Valid for first purchase only . I’m not able to use this voucher because I’m registered on Netflorist site.. I’ve NEVER in all the years ever made use of a purchase with a voucher code!!!! What a ****!!! Disappointed - will delete my profile & gaslight this Company…. Such bad business!!!!
