I've just noticed that I am being charged twice per month for the one subscription, anyone else having this issue? Or who do I contact?

 

Contact admin,I wouldn't expect a quick response tho!
Check your PayPal to make sure you don't have 2 recurring payments set up.
To cancel you have to do it from your PayPal.
It might be faster or should I say it WILL be faster getting a refund if you go through PayPal dispute.
