pranto,
you might get banned for applying to CIC if you further defend yourself for that cheating (WHO SAID HE CHEATED?) IELTS test report you have sent to CIC. CIC has a law on that. better an apology to them and swear to them that you will never do this again with anyone in your entire lifetime. practically Nothing will help you now. They have verified your photo on the test score report with the one held in IELTS authority and found a mismatch.
Did you apply by yourself or hired a crook consultant who might have done this to you without your consent?
Pranto,
Do not listen !!! Please go to British Council with all of your papers, application form, money receipt, result copy and letter from the SVO. You must carry a letter from you to British Council and request them to contact SVO before the dead line but you too contact. Do not keep silent so in future you will never able to apply again.
