Poor service from Lindt. Chocolate had weavels eating the hazelnuts.

Hi. Purchased a purchased this slab from. The Lindt Shop in Gateway. To our horror when we opened it had little weavels. Little bugs eating the hazelnuts. This is the first time ever we have experienced this. Product description: Lindt Milk Hazelnut 300grams Best before date: 20 - 10- 2025 L-Code: L1574 Place of purchase: Lindt Shop @ Gateway - Durban Barcode: 7 610400 013864 I have sent them a detailed email on the 1st of June 2025. Today is the 26th of June 2025 still no joy from them. I have made numerous calls to their office in Cape Town. They take down my details and never ever call. They sent me a very funny voucher to purchase more Lindt products. I appericated that but I don't have transport to get to the shops. And knowing the staff at Checkers Hyper will probably not understand the vouchers and end up giving me the run around. Please help. All I want is my new bug free chocolate returned. They fetched the offending chocolate.
