The expansion of free ad registration sites and the acceptance of users of these types of sites such as Sipur and Divar have caused some people to take advantage of the opportunity and look for fraud and profiteering in the ad sites. In order to prevent this action, experts active in the cyber field have mentioned some tips for users to buy and do transactions on the platform of advertising sites and to comply with their free requirements. . . . 1- Before contacting and making an appointment with a person, be sure to first get the name, manufacturer, and some other information about it through searching on the Internet and find out about its price. 2- Be sure to check the phone number and address of the transaction party first and make sure it is correct before making the transaction and paying the fee. Try to choose a product that is located in your city and place of residence. 3- If the price and terms of the product are too great, there may be a problem and you need to be careful. 4- Note that the ad registration with the image is not necessarily real. Therefore, you should never deposit money to the seller's account before viewing the product and checking its quality. 5- If the seller of goods provides his personal information or bank information, it is not a reason to trust him. He may have disclosed someone else's information. 6- Check the conditions and features before the transaction. For example, does the seller take back the product and refund your money if you are not satisfied with the product? This can increase the assurance of product authenticity. 7- In case you decide to buy a product whose price is high, arrange a contract for it and buy the desired product from the person according to that contract, so that you will not have any problems regarding the ownership of the product in the future. If it is not possible to set up a contract, get a written receipt from the seller. 8- The best deal is a cash deal; Checks and promissory notes may not be cashed. Also, cash transactions with large amounts are better to be done in safe places. 9- Never give your bank card information to a seller or a buyer whom you do not know completely yet. If the other party asks for your bank account information for no reason, there is a possibility that there is a problem in his work and you should pay more attention. . . ❌ If you just met us and you don't know how to choose your favorite engine, be sure to send me a message so that I can upload your information, both in terms of repairs and accessories. ❌ Akrami motorcycle spare parts started working in 2013 with the aim of providing service and supply of motorcycle spare parts with reasonable price and high quality, which was welcomed by many customers at the very beginning.
