Cannot assist a customer at CNA WHALECOAST HERM****.

I get a voucher for R2oo from my cousin in 2024. The store at whalecoast mall in herm**** did not stamp it. We went back in 2025 but they first told me the office are closed. The second time they said they did not have vouchers in January 2025. I think I will let it go but please people stay away from CNA in whalecoast herm****.
