The email address that sent you that response is most likely your VO's email address.i have once raised an enquiry in Aug 2019 and got the below reply.

and they also had an internal conversation which is listed as below as the same was also sent to me.
The last BF/due date for this client's application was 2019/05/20. The client is asking for an update on their file since no action was taken and delays have passed. Could you please verify?
In the above I aslo asked them for my VO but they didn't replied on that.
Moreover, I am unable to find any contact number where I can call them and ask for the update.
If it is Ottawa, the email address is cpc-ctd-ottawa@cic.gc.ca. I do not know the email address for other VOs since my file is in Ottawa.
The number to call is +18882422100, but it is only available to those in Canada or those who have a virtual canadian number through TextNow, Dingtone etc. It is quite difficult to call nowadays but you may be lucky to get through to them.
I hope this helps.
