Please I need advice.I applied for study permit offline from Cameroon in visa office in dakar. And on Wednesday the visa office sent me a procedural fairness letter that the bank statement document I submitted is fraudulent. And gave me seven days to respond to that concern by the visa officer. That if I don't respond my visa will be refused and I will be ban for 5yrs not to enter Canada for misrepresentation. I call the person who gave me the bank statement and he said he went and closed the account knowing that after 4months now since my passport is in dakar the embassy must have checked. So he had to use the money. But now he has another account in another bank and want to give it to me in the same name.what can I tellthe visa officer now.please help with ideas
