Upgrading tier on THC+

Where do you log in for the video membership site, as I’ve already paid for the subscription. I’d JUST paid mynormal, monthly subscription when less than a day later I saw the video membership offered and I jumped on it. Did I pay for the regular membership PLUS the video subscription which has the audio sub included? Can I get a refund on the purely audio sub? Damn. My English teacher from 6th grade would be flipping out over how that was written, but I don’t know the real names or titles of these shows.
