The bank may or may not require a police report to pursue a fraud claim. If it’s not fraud, it’s a chargeback based on your dissatisfaction with the product received. For example it could be that it doesn’t work, isn’t as advertised, wrong size etc. Some banks are very lienent and some are very strict.
A chargeback generally takes 30 to 60 days to resolve. An instant credit is usually granted by the bank, but if the dispute is not decided in your favor, the credit will be reversed.
