BidVertiser is happy to refund remaining funds in your account, however some restrictions apply.
In the event of a customer receiving free credit with a deposit, it is the customer's deposit that is spent first, with the free credit being the final funds to be spent. Any refund requested will take into account the amount of remaining funds from the initial deposit, excluding the free credit.
For example, customer A has made a $50 deposit, received $20 free credit. After spending $30 in clicks, they decide to receive a refund. They will receive $20 back to their credit card/paypal, and the free credit will also be removed from their account.
Also, in some cases old deposits cannot be refunded due to the excessive time frame that has passed, normally this is 6 months.
