You can send MOV.
I would ask for who is reporting the inaccurate information. Furnishers of information to the CRA have a duty to report accurately and they are not. You have no way of contacting the furnisher of the information to dispute if they do not provide the information of who is reporting it.
If they won't provide you with any information, then I would send ITS letter. Just make sure you are willing to actually sue if they don't fix it.
