Upgrade to 1TB plan is a joke

I was frustrated with the 20GB offered with the photography plan and was very pleased when Adobe offered a 1TB plan. When I checked the website today I saw the following

The upgrade button took me to my account page with no option to upgrade. The only way I could upgrade was to use the chat function. After waiting an hour (despite being told I would have to wait 6 minutes), I finally chatted to support. I was told I had to cancel my plan and then he would sign me up for the new one. I did this but then support couldn't add the plan and I waited another ten minutes to be transferred to sales where I had to start the whole conversation again. Sales then informed me that they couldn't add the plan and I had to make the purchase over the phone - seriously! This is 2017 not 1987. I've been on hold for half na hour. So two hours after deciding to upgrade, I now have no plan with Adobe and seriously thinking about going elsewhere. By comparison, changing storage with Google or Apple takes less than 30 seconds.
