Awful service. Tried to renew my annual membership (in fact tried to upgrade to a joint senior membership) and managed to speak to an advisor and was advised that my payment datails had been taken, and the renawal would be completed off call, and i would receive an email which would act as a membership confirmation pending delivery of a new card. To date 8/2/23 to 16/2/23 no such e mail has been received. Furthermore my membership appears to be still showing renewal required.I have tried to contact an advisor, but kept on hold for over 20 mins on two separate occasions..I have also sent 2 x e mails which remain unanswered.Very poor customer service, and experience...Ive given up the renewal process and this after being a member for some years.Get a grip National trust..
