Card details not updating in clientzone

Once again Afrihost have shown how pathetic they are at customer service. for 3 months now i have been charged a penatly R50 fee for a bounced account payment due to clientzone error not updating my card details. I recieved a new bank card and every month went into clientzone updated the debit details paid the R1 update fee, it then confirms its updated and end of that month it bounces and Afrihost charges me R50 fee even though its their system error. Today i spoke to accounts and they informed me i will not be refunded because i should know to use different web browsers if it does not work even though i only knew when debits bounced. RUDE service and a pathetic company.
