Tennisboom.com understands that sometimes customers may need to cancel or modify their orders after they have been placed. However, there are specific guidelines regarding this process. Once an order is submitted, it is typically processed quickly to ensure timely shipping, which means there is a limited window during which cancellations or modifications can be accommodated. If you realize that you need to make a change or cancel shortly after placing your order, it is advisable to check the current page on Tennisboom.com for specific instructions on how to proceed. Additionally, it is best to act quickly, as once an order moves into the shipping phase, it may no longer be possible to modify or cancel it. Make sure to gather all relevant order information when seeking assistance, as this will streamline the process.
