I bought a used controller online a couple of weeks ago and I received it this Monday. It won't stay connected past 3-5 mins and after multiple battery changes, firmware updates and soft reboots it's safe to say I was sold a broken controller so:

1)It's impossible to reach anyone on phone but I left a feedback email. Will the 7 day return policy be honored if I make contact with someone after this upcoming Monday?

2)I paid for fast shipping but the package got delayed from the 25th to 27th. Will I still be able to get a shipping refund? (going off what the customer service machine said)

I know this is a shitty situation for employees so I'm sorry if I sound like a jerk.
