Bad service

Good day,<br> I'll keep this short and to the point.<br> I app**** for a replacement primary card, and a new secondary card. I instructed and was assured that they would arrive at the same time. I go collect and after 30 minutes I find out only the primary card is at the store the secondary was POSTED for some reason.<br> Secondly, I received a Vitality HealthyFood Switch app voucher. None of the staff knew how it works. I pick up the foods, at the till the voucher doesn't work. For a solid 90 minutes, I wait while everyone tries everything. Head office is called, with no resolution. Then I am told I can't use the voucher because there's something wrong with it, and I must go home and come back in a few days when it is resolved with Vitality because they sent the incorrect voucher number. Both managers on duty think that's a perfectly fine for a customer to waste their time, because it's a Discovery fault not theirs. While I am being told I must leave everything and come back, a staff member enters the number correctly and it works. <br> This whole time all the staff, managers included, were wasting my time, not entering the complete number as it appeared on the voucher.
