Q: rented movie on apple tv.  now attempts to download on my iphone. cant get it to stop

COMPLETELY RIDICULOUS.  Rented movie on new apple tv.  Said I had to verify on my pc.  Didnt work.  googled it.  forum said to change my payment info.  I did this.  Then apple tv said 'you've already purchased this rental' 'do you want to purchase again?'.  NO. I DO NOT.  logged in to itunes.  has two downloads waiting.  1.) is walking dead (in which i've tried to delete but itunes will not delete it), the second of which i can only guess that it is the movie i rented. 

this is communistic crap to be very honest.  ive had to input my freakin password 80 million times.  cant do this. cant do that.  you've got to be kidding me. 

although i've got little confidence please help me.  it's further ridiculous that i have to go to an 'apple community' to get help.  how about freaking APPLE helping me? huh?  It's not a community. it's crap. probably going to be my last straw w/ apple.  going to google unless this is an easy fix.
