While there's plenty of explanation of the fact that Skinny prepaid accounts expire after 12 months of not topping up just like other providers, I can't find any way of finding the exact date.

I'm an ultra-low user, so I only need to top up once a year. I don't like relying on SMS notifications because sometimes they don't come through, which I accept is the nature of the service.

Can't find the date on the online portal, nor in the USSD menu. 

So unless I've missed something incredibly obvious, I would really like it if it's put online like all the other providers.
