Waiting since February for new membership cards

Afternoon,<br> <br> I have requested 2 new Membership Cards (1 for me and 1 for my son who attends Boarding School) because I married and my surname changed, but my son's stayed the same. To date I have received cards BUT ON THE OLD SURNAME (was sent to me twice on the old surname). Please tell me why I as paying member should keep on e-Mailing and calling you but you do not respond? Is your staff not trained well enough to be efficient and effective? Or do you not have enough staff and overload your staff? Curious.
