When did you top up?
What day of the month does your membership normally expire?
What does your online account say about your membership status/type and expiry date?
Any chance you bought a new membership while you had an existing membership in place which had time to run?
If so then the newly purchased membership will have "stacked" to kick in when the current membership (and any other stacked memberships) has expired.
All memberships run their full monthly course.
Buying a membership while you have a membership in place with time to run does not prematurely terminate the current membership.
If you have used up allowances on a current membership you may need to buy a suitable add-on to tide you over until the current membership expires.
Hope this helps.
