If you paid £49.99 it was for lifetime, not for a year.
Did you make sure your card details were kept up to date as

How did you contact support, via the contact me page, or via email?
If email which email address did you use?
Whichever way you contacted them you should have received a automated support ticket, almost immediately followed by a proper response fairly quickly after.
If you did not receive an automated ticket number, eBid did not receive your query.
