Since you used pounds as the currency I will assume you are in the UK, if so the GDPR applies and you might be in luck in terms of recovering your data.

If you see an option to download your data on the "account suspended" page, use it, or try to access the feature directly: https://www.facebook.com/help/212802592074644

That should at least give you an export of all the media uploaded by the account.

If you can't, it might be worth getting in touch with the ICO or a pro-privacy non-profit such as Open Rights Group (https://www.openrightsgroup.org) or NOYB (https://noyb.eu/en) and ask for advice on how to do a subject access request to manually get your data back, and on top of that why not request a manual review of your account suspension (the GDPR mandates that a data subject has the right to request a review of any automated decision).
