If you are concerned that duplicate transaction has occurred send us an email to help@kabirsprep.com or call us at (248) 973-7452 and we will reverse the transaction. Please be aware that any declined transaction will be listed as pending on your credit card for up to 7 days as a security feature instituted by credit card companies. Unfortunately, we cannot reverse this charge since it is not an actual charge and we have not taken any payment. Please communicate with us directly and we promise to resolve any issue from our end as much as we can. We take payment concerns very seriously and have a strong payment system that prevents against double charges.
