hi good day.few days ago i tried this immigration consultancy,the canadianvisa expert.they called me and ask me stuffs like my name my income and sorts they even asked about my card which i gave them even the 3 security number at the back.fortunately this cards is like debit cards which i havent put any cash in.now they sent me an email asking me to pay 425dollas.which they says i owed them already.they said that i should take action within 10 working days.should i be worried?and did any of you experience this thing?
