Q&A

Ordering Process

1. Automatic: After making an online payment, click the (Download) link to download the source code; 2. Manual: Contact the seller or the official to check if the template is consistent. Then, place an order and make payment online. The seller ships the goods, and both parties inspect and confirm that there are no issues. ICTcoder will then settle the payment for the seller. Note: Please ensure to place your order and make payment through ICTcoder. If you do not place your order and make payment through ICTcoder, and the seller sends fake source code or encounters any issues, ICTcoder will not assist in resolving them, nor can we guarantee your funds!

Transactions and Disputes

1. Default transaction cycle for source code: The seller manually ships the goods within 1-3 days. The amount paid by the user will be held in escrow by ICTcoder until 7 days after the transaction is completed and both parties confirm that there are no issues. ICTcoder will then settle with the seller. In case of any disputes, ICTcoder will have staff to assist in handling until the dispute is resolved or a refund is made! If the buyer places an order and makes payment not through ICTcoder, any issues and disputes have nothing to do with ICTcoder, and ICTcoder will not be responsible for any liabilities!

Matters needing attention

1. ICTcoder will permanently archive the transaction process between both parties and snapshots of the traded goods to ensure the authenticity, validity, and security of the transaction! 2. ICTcoder cannot guarantee services such as "permanent package updates" and "permanent technical support" after the merchant's commitment. Buyers are advised to identify these services on their own. If necessary, they can contact ICTcoder for assistance; 3. When both website demonstration and image demonstration exist in the source code, and the text descriptions of the website and images are inconsistent, the text description of the image shall prevail as the basis for dispute resolution (excluding special statements or agreements); 4. If there is no statement such as "no legal basis for refund" or similar content, any indication on the product that "once sold, no refunds will be supported" or other similar declarations shall be deemed invalid; 5. Before the buyer places an order and makes payment, the transaction details agreed upon by both parties via WhatsApp or email can also serve as the basis for dispute resolution (in case of any inconsistency between the agreement and the description of the conflict, the agreement shall prevail); 6. Since chat records and email records can serve as the basis for dispute resolution, both parties should only communicate with each other through the contact information left on the system when contacting each other, in order to prevent the other party from denying their own commitments. 7. Although the probability of disputes is low, it is essential to retain important information such as chat records, text messages, and email records, in case a dispute arises, so that ICTcoder can intervene quickly.

ICTcoder reminds and declares

1. As a third-party intermediary platform, ICTcoder solely protects transaction security and the rights and interests of both buyers and sellers based on the transaction contract (product description, agreed content before the transaction); 2. For online trading projects not on the ICTcoder platform, any consequences are unrelated to this platform; regardless of the reason why the seller requests an offline transaction, please contact the administrator to report.
