It is a phone number for Canadian Visa Professionals.
However, Be aware! - it is Not a government service. They have a false advertisement.
If you thinking of signing up for their services I would strongly recommend you Not to do so.
Do not provide to them your credit card information.
If you already have signed up with them, Do freeze or cancel your account. Also, Cancel your credit card, If they already have it on file. Otherwise it will cost you a fortune.
