Avg pro and cleaner

Hi there! I bought this avg pro and cleaner on June 15, 2016 at play store it says on Sale 50% off and will work on all devices. Phone (android or apple), tablet and computer. Now I installed it all to my devices, it is working (except on my apple phone) but it says I only have a free trial and it is only good for a month. So what is the sense that I paid for it. Tried to contact your sales and billing support 3x on the phone but can't still fix this issue. Honestly speaking I don't usually buy this kind of stuff because I can get it for free. But I never thought buying this stuff could pissed people off. I bought it and still have the free trial. I'm hoping that you and your support team here could help regarding this issue if not so I would like to ask my refund. I'll appreciate any help your team could extend. Thank you. Best regards.

So where should I message the proof of receipt? Now I rather have refund than using your app because it really pisses me off right now.

Hazel, Also I'm afraid currently AVG don't have any products to suit iOS devices.
