Poor customer service

My favourite is choice assorted, I purchased a box of choice assorted biscuits on the online app, in the month of March. Opened it the very next morning, , it was a sealed packet. The biscuits were missing, it was noticeable and very stale, I immediately took pics and emailed bakers the very same time.

It was about 4 days later when a consultant had called me to say she would replace by sending a wi code voucher . I tried using it on the app , it read invalid, I then drove to the store were by 3 cashiers tried it and it still read invalid.

I then sent an email to bakers stating my experience , I also emailed, which I then received the second voucher which says invalid, i then sent the third email, its now 2 weeks i have not received any call or message from them.

Extremely poor and bad customer service.
