Double subscription; Which one ends first?

[jp774477]

Hello I need help badly. I subscribed to Premium on 6/16/17 which means my service will end on the 07/16/17. For some reason or my own fault I suddenly received a text message from my credit card bank on 07/07/17 for Spotify and when I checked it was Family Premium so I cancelled immediately thinking maybe it was on auto-mode to rollover on that date. Now the Subscription and Payment page says my Premium for Family will end on 7/8/17?? If I have already been charged as checked with bank why would it end in just a day? How about my first subscription of Premium will that end as well. Hoping you could help reverse since I was just viewing how Family Premium works and for some reason got charged even when I do not remember ordering latter. Will try to attach the receipts below.
