1. First of all, you can try to negotiate with the health center, ask the reason and process of refund, and see if you can solve the problem of refund through negotiation.

2. If negotiation fails, you can submit a written application to the health center for refund of the paid fees. When applying, you should state your basic information, card date, card type, amount, reason for refund, etc. , and keep the copy and the original.

3. If the hospital does not agree to refund the fee, it can apply to the relevant departments or social organizations for mediation and solve the problem of refund through consultation. For example, you can complain to Dezhou Consumers Association or apply for arbitration to Dezhou Industrial and Commercial Bureau.
