Hi @meany84 thanks for your post although I'm sorry to hear of your concerns raised here.
This can sometimes happen when you've moved addresses, or you've left and re-joined us for example (it can go from 01 to 02, or 02 to 03).
Please allow me to send you a PM however so I can look into things further for you. Kindly expect the PM from me to arrive shortly and respond directly when you can!
Many thanks
Tom_W
