Amazon charged me twice and won't refund the second charge
So this happened a couple hours ago and need some feedback on how to proceed.
So I live in the USA but am from Canada, I use amazon.ca for psn gift cards as I can't get Canadian ones here in to USA.
Anyways, I place an order for 1--$100 dollar one and 1-$50 dollar one. 10 minute went by I got my order complete but it only included the $100 one. I waited an hour and decided to talk to chat. After na hour with them they couldn't figure out why it was processed seperate. Finally I asked if it would just be fast to cancel that order and reorder another one. She said she would cancel it and I can reorder. She stayed online with me til I processed the next order. Figured that was that and I'd just wait for the order to process.
Fifteen minutes go by and I get 4 emails. Both transactions went through. So I go back and reach out to them again and they refused to fix it, refund or credit me because it has to do with video games. Eventually I got pissed because after 2 hours of being on with support I got no where.
What can I do? Is the only option to charge back with my bank?
