*********** Voucher system

I received a fishaway voucher on Friday evening 20 Jan, after purchasing a meal from Steers. The voucher is valid until 31 Jan code ***. I tried to redeem the voucher on Sunday 22Jan . I was informed that the code is invalid as it was already redeemed. It is disappointing that Fishaways has such a Weak *********** system . Are you printing vouchers with the same code to use as tactic to get people to your door??. I end ip paying for the meal which was a bit disappointing. The voucher nr could only be leaked by staff as the voucher was not publicly exposed. Rather disguise the code and force the client to expose it in scratch card format. Alternatively keep your system and fish- off more clients .
