Hello,maybe someone had the same situation like me.I applied aug 8 for my naturalization,I received a letter yesterday dated Aug 14 that when Ukba took the payment my card was declined.There is enough money in my account.i phoned the bank and told me that theres no transaction in my account that the HO is taking some money in my account.If someone out there got the same situation with me can u pls advise me what did you do,I send again another payment slip thru next day delivery post.hope this one will be fine and no more hazzle because its a waste of time waiting.thanks,
