If online shopping is cheated, first contact the customer service and complaint agency of the shopping platform to make a complaint. If it doesn't work, contact the network police to report it. For the independent shopping website of the merchant, contact the network police directly to solve it.
Techniques to prevent the network from being cheated;
For independent e-commerce websites, choose regular filing websites and businesses with good online reputation.
For shops with platform nature, choose shops with excellent sales volume and evaluation.
Don't be greedy and cheap, and don't trust the so-called "refund phone" easily.
Don't enter your bank card and personal information anywhere outside official website.
Keep relevant evidence, such as screenshots and phone records.
