Regarding Cancellation of Representative

Dear Sir/Madam,


I am the principle applicant and applied Immigration to canada thro Consultants. I have applied on July 2005 and got file number August 2005. Recently I have forwarded all the updated documents and My Sister's Details who lives in canada and Notarised documents of Her passport for my sponsorship to canada to consultants and they informed that the documents have been sent to Canada High Commision on 13 th Oct 2009.Many times I approached my Representative that is consultants, they are not telling , when shall i get immigration ? So please tell me when shall get Medical Test and Immigration Visa?.Moreover , i have got 6 in ielts and also IELTS score card has been forwarded to consultants. Now they are saying , Ielts 7 band is prefered,Also they are informing , Degree M.Tech and Experience gained after file submission to immigaration to canada , is not considered for evaluation. Now I have decided to cancel my representative and I need to know that the cancellation of representative will affect the application status or not. However, Canada High Commission told that if I cancel representative , your change of address will be updated in file only not in cic.gc.ca. website.

Please guide me how to handle this task.

Regards
