Multiple charges can happen due to various scenarios, below are a few examples:
If you added additional products to your trial.
Authorization charge from your bank. You can find more information on that, HERE.
If you cancelled your subscription immediately after signing up, then reactivate the subscription. This not only creates the possibility of your trial kit not shipping, but you'll also get charged for your next kit, based on your selected plan pricing.
If you adjusted your next billing & shipping date immediately after signing up or immediately after getting charged for your next kit. When doing so, it confuses the system automation which may cause your shipment to be postponed and another charge on the date you selected. As a result of the change, both kits may ship.
*Please keep in mind that the MDhair service is a subscription. If you need to make any changes or need to cancel your plan, kindly do so prior to your next billing date, so you don't risk your next kit from shipping. Once you are billed, the information about the shipment is sent to the warehouse for immediate processing. Once at the warehouse, the shipment may not be able to be stopped. Please be mindful for the changes you make on your account.
