I have been waiting for a refund on a duplicated purchase since discussing the matter on 20-04-2025 on live chat. the reference number is case reference number: 23099253. and chased again on 29-05-2025 case reference number 23262808. Please advise on refund as this has been going on to long. It is now 13//07/2025 and still had NO refund. How much longer do I need to wait before I take legal action.
