playster continued charging credit card despite acknowledgement of cancellation New York, NY Internet

Playster offered free access to an ebook during a 30 day trial period starting August 9, 2016. The promised ebook was not actually available from Playster and I informed them immediately. On 8/26/16 I canceled my subscription which was finally acknowledged via email by a customer service representative. I checked subscription status again 8/26/16 and made a second request to cancel which was again confirmed by customer service agent, Sophie. On June 5th, 2017, my wife informed me that playster was still charging our card for a subscription. After contacting playster, they agreed to credit us for the last 6 months (24.95/ month) but not the first 4 months as it was not possible within their accounting system to do so.  Shortly thereafter, I sent the CEO, Phil Keezer a letter via certified mail including hard copies of my past email correspondence requesting a full refund from 8/9/16. I have not yet heard back. I also contacted him via his linkedin page.
