Bad Customer Support Experience

I pre purchased Battlefield Pro ahead of Season 4

On 22nd July I logged in and got my instant unlocks

But the instant unlocks, specifically a certain weapon package, were not available to equip

The weapon package directed me to purchase battlepass, so I thought I had to buy it and paid BC for it

But I understand battlepass is included in pro, I shouldnt have been able to purchase it again

I logged out and back in, and all my unlocks were then available

I contacted support and spent an hour on 2 chats trying to get the BC refunded.

The first support agent told me to flush my dns then ended the chat session.

The second agent told me he simply couldnt help.. sorry, then ended the chat session.

I dont feel like the game should have allowed me to make a purchase I had already made.
