I have had a similar issue. I tried canceling at the 14 day trial and they indicated I did not meet the cut-off because of the time difference. This was in 2015. Fast forward to 2017 and I just got a collection letter. I provided them proof of me trying to cancel in 2015, but they indicated unless I have a cancelation confirmation that I still owe. Has anyone had experience with this? Did this get reported on your credit?
