Netflorist stinks

Despite receiving a voucher from Netflorist (to be used within 2 hours) I was unable to use it- their website kept on saying “oops Harold broke it” So eventually I had to phone. Fifteen minutes later and holding for someone to help I was eventually advised by the manager that it’s IMPOSSIBLE for their computer to generate a code that begins with an “A” despite having the voucher in front of me. I was asked to email him a copy of the voucher which I did. Needless to say I have not received an apology for not ‘lying’ and neither have I received a replacement voucher. Shame on you Netflorist..... I have used you for years but perhaps you’re too arrogant to know that you have competitors
