A feature of Bitcoin network is system of confirmations. Normally, your payment must have at least 3 network confirmations before it will be added as deposit. It may take from one to two hours. In rare cases, you may be faced with the expectation of up to 24 hours. We have no influence on the speed of this process, and can only recommend to wait a little after sending. In any case, your deposit will be added sooner or later.
