I have had duplicates sent, I'm on a 12month sub, international, and twice now I've had additional 3month sub renewals come out my bank account. So to anyone that is getting double deliveries just check you're not actually getting charged.
Each delivery had a diff sub number which will confirm this is the case. So they're sending out two records cos they think you have two subs, and in my case they charged me for two.
Quickly resolved and refunded. But worryingly it happened again at the beginning of what would be the next three month period.
Fingers crossed it doesn't happen again.
Last time I was actually on a 3 month sub was about 2 years ago when I first signed up.
So anyway, please double check you've not been charged.
