Character Gone Xbox

Haven’t played game in months but have sunk over a hundred hours easily into this game. Decide to download and play on my new xbox for my character to dissappear. My test character save loaded fine, my secondary and my main characters are lost. I have tried all options from across the Internet and this forum and nothing works. After locally deleting save file first time didnt work I tried again and now I’ve lost the other character too. I’d like someone from the company to get in touch with me please so they can rectify this mistake asap. Thankyou
