A deposit can fail for many reasons, from simply entering the wrong card number to problems connecting to servers. Please check whether there are no connection issues before considering the following options:
• Check if there are enough funds available, sometimes unexpected bills can surprise them so it is important to check that the funds are there to use.
• Sometimes, for new vendors, or if large amounts have left your account recently, your banking provider may temporarily suspend your account from use. Contact your bank to check that they haven’t suspended payments from your account.
None of these options? Please feel free to contact their support team at any time of day.
