Once a complaint is submitted by a user or advertiser, Door will investigate the issue and allow both parties to provide details. If the complaint justifies a reversal of payment, Door will deduct the payment from the user's account and deposit it to the advertiser's account. If the complaint justifies the discontinued use of data by an advertiser, the advertiser's account will be placed on hold and all affected data will be removed from their account with no refund or payment.
