The only way that 48 can charge you money is if you manually buy stuff or auto-renewal renews your regular membership plan.
48 can't unilaterally charge you anything otherwise.
What does your Transactions page say about recent payments?
What does your My48 account Dashboard say about your current membership status, allowance balances and expiry date?
Does your Buy Plan page list any upcoming memberships?
If you need to contact 48 support about this then see the link in my signature below or email them at support@48months.zendesk.com
