So, does your reply reach them? Who knows. Now you have to set yourself a reminder to follow up and make sure the request got through.
Alternatively, you hunt down their support email but you still need to follow up.
Then there are the rare times a company fights you on it. Then you have a whole back and forth before they finally capitulate.
I personally go through the hassle but I can understand why OP wouldn't want to.

Plenty of people have taken me up on the offer for a refund, and none of them felt the need to "yell", so I think they got the correct vibe. All our site copy and mails have this same casual, friendly tone. People seem to like it.
Casual tone is one thing (a good thing), but I posit that an actually angry customer will not respond well to this.
"Oh damn I get this email again... and they are telling me I can cancel, but I think I already cancelled... wth. Hmm, maybe they'll give me a refund."
Now at that point whether the customer is right or wrong they'll read the yell part and think that you are mocking their potential interest in demanding a refund.
Maybe I am totally alone here (with the other guy I guess), but while I wouldn't go dispute a charge myself that wording of yours would not encourage me to write in and get my hopes up you are happy to accomodate me.
For better or worse, the chargeback is the only weapon end-users have anymore.
Why involve the telephone?
