The text that tells us when the premium trade renew is happening is inaccurate or using some time zone that is not in the US even though my time zone is correctly set to Pacific US.
On the corecoins history page the time stamp for the transaction is listed as over 6 hours *in the future*: "11-26-2017, 05:47 AM"

I was going to cancel my auto renewals before the new week started but since the time listed is wrong and/or the deduction is being taken early, I missed my chance to turn it off.
Since they are post-dated, I am requesting those last 2 Premium Trade charges be credited back to my corecoins total.
