I was wondering if DLC could be transferred from console to pc because I have just bought it on console and I am planning to get it on pc and if it is possible it would save me money.
No, it's not possible to use it on PC without paying for it. As an alternative you might be able to get a refund from whoever you bought the console version from but you'll have to investigate your options there and perhaps argue the point. From what I've heard refunds have been provided before on console versions.
It is currently possible to get a refund on Xbox Use the following link and replace the info with your xbox account details. Note: Most refunds can be made if the item was bought within 14 days or 2 weeks https://support.microsoft.com/en-us/supportrequestform/ce13499f-dd3b-8dfc-cc0a-4ab23f66218c
Yes, if you have a Microsoft computer then put both your xbox and pc to network transfer ensure both are on the same internet connection then go to your xbox and confirm the transfer. You can also do this with an external source plug it into your pc save all storage onto the external USB then plug it into your xbox to transfer all data. Hope this helped. If you need anything else just reply to this and I'll get back to you.
