Hey Onlyy44,
I had the same situation like yours. Also i did not had any tracking info for the medicals that my doctor sent because he sent it ordinary post. So i was not sure if my medicals reached ottawa or not. I emailed Buffalo with the above query and i got a reply from them the very next day that they received my medicals.
"BUT MY ECAS STILL DOSEN'T SHOW THAT MEDICALS HAS BEEN RECEIVED"
My medicals were done on July 28 and i can assume it might have reached ottawa in first week of August.
Contact Buffalo from the contact page from cic website rather then sending them a email from your personal email account.
Hi thank you for number - I try call her but every time I get answer machine.
By the way i s almost 3 month after they start process my application and 2 months after my doctor sent medicals - and still nothing

( nothing on ecase, nothing form buffalo and when I call canadian office ask if my medical are on there system they say no - so I am so sad

(
