Adobe complaint escalation EU

Hi,

Could anyone please advise on the complaints process or contact for Adobe EU. I had a horrible exchange in the support-chat and would like to get in touch with someone that could help me with my problem. 

Today my credit card bounced an auto renewal of my Creative Cloud subscription and I while I was in my account I found my attempted bill at my correct prics. 
BUT at the same time I could see that the cost of my Creative Cloud subscription was planned to increase by over 500 EUR in october of this year.

Shocked by the price increase I turned to Adobe support for clarification. 

Without sharing exact logs - the exchange proceeded as following: 
Me: Why is my subscription increasing by over 500 EUR? 
Rep: Sorry to hear about the price increase we like to inform you that you have joined the applications with the dicounted price. But I will definitely assist you with the price. We need to cancel and assist you with the repurchase same application as the plan is in Grace Past Due. 

Me: I do not understand what this means.

Rep: To change plan price we need to cancel this current plan and we will assist you with the repurchase the same application. 
Me: What are the implications of cancelling and repurchasing the application? What changes in my terms of service? 

The Rep. proceeds to promptly cancel my plan without informing me. I only noticed due to it locking me out of all my software that I was, at the time, using to finish up a projekt. Note that I still had an agreement up until october of this year. 

I press him to clarify why he just cancelled my plan were he reitterates that he had to cancel and can offer me a new agreement for 150 EUR above my current rate.

I once again press him on why he cancelled my plan and in addition added 150 EUR to my subscription cost. 

He offers me a discount of 113 EUR putting me close to my original agreement. 

I reiterate that its still not the same cost as my original agreement and that I'm unamused by Adobe increasing my product by 500 EUR and hen him cancelling my subscription with almost a years subscription remaining. So I ask for instructions on how to escalate this matter within Adobe. 

He ignores my request twice and offers me a discounted price of 63%, followed by 2 free months to my account until, finally, the option to speak with his boss. 
I agree to the only means of escalation wherefrom the boss connects to the chat, thanks me for patience and promptly terminates the conversation. 

I now stand without any subscription and a handfull of projects to complete and need help reinstating my subscription. How do I proceed?
