CNA received money for a voucher that does not work.

I received a voucher in 2024 from a family member. The staff member at Whalecoast Mall in Herm**** did not stamped the voucher. When I want to use it now in 2025 they are full of excuses. So people stay away from CNA in Whalecoast Herm****. They do not do there work now I must sit with a voucher of no use. Be careful please.
