Out of personal experience with being hacked I will give you this information. Contact Live Chat Support. They are incredibly helpful! They can tell you when your account was last accessed, and if you were hacked and purchases were made I can almost guarantee
your case will be resolved. When I went through this process I calmly described the situation, and how I lost 60$ worth of MSP from purchases I didn't make, and during my time of being off Xbox [30 days]. The servicer was incredibly helpful, gave me a phone
call and some information. She told me my account was suspended for 5 days while information is found out about the hacker.

.

After the 5 days my account was released with a new email and password, and I was refunded my points, the person received a console ban and I'm fairly positive law enforcement was brought in for theft. The worst thing you can do in a case like this is not
try to get it dealt with.

Did you set up any security proofs,an extra email or mobile phone number for example?

If you haven`t you will have no chance to get your account back,without an email or password.

Sorry but if that account was banned then you forfiet any games,dlc etc that was bought with that account.

You will have to pay full price for the game if you buy it with a different account.

Your other account will not be "unbanned" just so you can get Minecraft at the discount price.
