Upon your written request, any unused amount after account cancellation, above the initial £60 non refundable deposit, will be refunded to the credit card that was used for payment. However, your final refund credit may reflect charges for additional clicks occurring between the initial request for cancellation and reasonable lag times for processing of your cancellation.
