Hi there,
We're sorry to hear about your experience. Our policies are in place to ensure consistency and fairness for all customers. Regarding the return policy, we must adhere to sanitation guidelines, which unfortunately means we cannot accept returns for opened or used cables. For products that have been opened, such as headphones, amplifiers, etc., we support return and refund within 7 days.
Regarding replacement wires, we strive to provide assistance to all our customers. We did recommend suitable replacement cables for your IEM in our email reply on February 13 at 19:39. Please review our email correspondence for the provided cable link.
If you have any further questions or concerns, please don't hesitate to reach out.
