How can I file a complaint?

A while ago I noticed that my credit card was being charged twice by Adobe in the amount of $21.31.  Further research showed that I had also been charged twice in 2014 and twice in 2013 for the same amount.  That's a total of $42.62 per year for three years.  I contacted Adobe customer service to find out what these charges were.  I was told it was for my subscription to Adobe export pdf, and the reason I was being charged twice is because I had the subscription under two different email addresses.  When I first purchased Adobe export pdf  I  was never told that it was going to automatically renew, and I was never alerted in advance of the upcoming renewal and charges to my credit card.  So I have an issue with being charged for a renewal without any prior notice.  I am assuming that when my email address changed I started getting charged for the automatic renewal on both the account tied to my new email address and the account tied to my old email address.  I also have an issue with getting charged twice for the same subscription. When I updated my email address in my Adobe profile, the old email address should have been purged and I should not have incurred the additional charges.  I asked that both of the subscriptions be cancelled and that I get refunded $42.62 for the charges that were incurred in April of this year for the 2015 renewals.  I also asked that I get reimbursed for one of the two charges incurred in both 2014 and in 2013 since I should have never been charged twice for the same subscription.  So that would be a total of $85.24 reimbursed back to me and a verification that both of the subscriptions are cancelled.  I was told that the subscriptions would be cancelled immediately and to wait 5-7 business days for the money to be refunded into my account.  When 7 days passed, and there was no refund, I contacted customer service again.  I was told there was a "glitch" in the processing and to wait another 5-7 business days for the refund to be completed.  This exact scenario has happened at least FIVE times.  No refund, a "glitch" in the processing, and an assurance that the issue will be resolved in 5-7 business days.  I am told that chat is the only way to communicate with customer service.  Nobody will give me a telephone number of an actual person I can talk to, and this issue continues to go unresolved.  Dealing with Adobe customer service has been one of the most frustrating experiences to say the least. Not to mention the amount of time I have wasted on this issue.  I need to speak to an actual person and to have this issue resolved.
