Customer Service completely unresponsive/unhelpful and altogether awful despite them overcharging my co.

I would like to share my response to my most recent customer service case being closed because I didn't contact within the 4 calendar days (which included a weekend) despite having contacted you TWICE during that time:

Your customer service is literally the worst I have ever received of any company.

1. You wasted probably two days worth of two of our employees time because they had to contact support NUMEROUS times over many months trying to resolve our issue.
2. At our last waste of time I spent 145 MINUTES on the phone trying to get this resolved (with 2 separate people) only to be told they can't do it and that someone higher up would take care of it and then get back to me.
3. You did NOT take care of it and then referred me back to our Account Manager AND gave a ridiculous 4 day (not even BUSINESS day) limit to do so.
4. I contacted support immediately and responded to that response telling them I wanted to speak to someone right then. They referred me back to the Account Manager.
5. I then ALSO contacted our Account Manager and let him know I was being forced to contact them despite no response in the past. I am sure you can see where I am going with this - NO RESPONSE AGAIN!
6. Today I get a notice this case is closed because I didn't contact within 4 days. This is the part that may have literally caused a slight aneurysm of frustration.

You do not entrust your customer service people to solve issues. You force them to speak to a customer and if it's not the most basic of issues they are unable/not empowered to handle. You refer up to people that ignore our issues. You put unattainable time limits on our inquiries - I have to assume so you can avoid helping people. Even when we do contact service within the time limits you close them anyway. And the whole reason I have been contacting Adobe is because you charged my company DOUBLE what i should have been charged for almost 2 years. Once discovered you gave a partial refund and dropped our case immediately despite numerous contacts right afterwards letting you know that the refund wasn't correct. I provided a spreadsheet of credit card charges by date, a timeline and an exact dollar amount we were overcharged to customer service. I received no response. I have probably never been so angry at a company. I have to assume at some point you think I'll give up because my time is more valuable than the money I am owed. Well I won't. I am not going to let you take money you had to right to take. I will continue contacting Adobe non stop, wasting time and valuable company resources, because what you've done is wrong.

The file I just gave you shows that in December of 2015 we were offered a group license product. That month we were charged for 4 individual licenses AND the group product price.

That month someone must have realized we were overcharged because we received one individual license refund. Thereby leaving us overcharged in December of 2015 for $161.97.

Thereafter for the next 9 months (from 1/2016 - 10/2016) there was a $215.96 overcharge = $1943.64 total overcharged. Then finally,

For the 9 months following that (from 11/2016 - 7/2017) there was a $64.80 overcharge per month b/c our rate was changed back to the individual licenses instead of the group price. That added another $583.20 in excess charges.

Grand totaling $2688.81. The refund we received was for $1079.78.

We are due $1609.03 after you deduct the first refund.

I would like someone with authority to fix this issue to contact me or i will continue posting this in every forum I can get access to so that your customers know this is the way you handle issues such as this.

Please forum - please tell me how I can get real help from someone.
