Anyone successfully cancelled their VidIQ subscription?

SO I had VidIQ last year and I paid $400 for it. I didn't realise it was set for automatic renewal so as I don't use it any more I've still been charged via Paypal.

I tried to contact them to cancel it but they said there are no refunds once cancelled which I think is pretty unfair, especially as I did not know it would get renewed.

Does anyone have any tips on how to get my money back or is it long gone?
