Are you sure that the auto-renewal mechanism is able to renew your monthly membership plan or is it failing for some reason?
If it's working and renewing your membership plan ok then maybe just ignore the messages?
If it's failing then maybe your registered payment card is no longer valid and needs to be updated, or it's frozen via your online banking, or there aren't sufficient funds in the account if it's a debit card?
When was auto-renewal working ok for you without these messages last?
If you need to contact 48 support about this then see the links in my signature below.
