Chat assistant sent me a suspicious email then cancelled my plan, who do I tell?

I spoke with Deepak about editing my payment plan because there were no buttons to do so on my account page. This chat was through the official adobe.com support chat. Deepak offered me a better price on the All Apps than I was currently paying. I was sent the email below and told to use the link to submit a payment. This email is very suspicious. The address is a gmail.com not adobe.com. Trustechauthority is the email and merchant name, but the sender name is Adobe Support. The link provided takes me to a poorly designed page that does not use a secure connection. All things things I don't expect from Adobe.

Edit: I was going to paste the link I was sent but there is no reason to help their SEO. Trust me when I say that it has nothing to do with Adobe.

I told Deepak that this doesn't look legitimate. He then told me that If I don't want to pay this way I can edit my plan through my adobe account page. I checked my account page again and the buttons to manage and edit my plan reappeared.

I then closed the chat. Immediately after, I received a legitimate Adobe email saying that my cancellation was successful. Now I cannot open my CC apps and my typekit fonts were unsynced.
