Thatcher's Organic Compost

Has anyone used this stuff or know anything about it?
I got three 70 litre bags for £10 which seems super cheap. On the bag it says 'Organic Multi-purpose Compost Blend'. There are no ingredients listed just says it's good to grow different crops in it and has the make 'Thatcher's' in green. I didn't buy them in the shop, I paid someone to get organic compost for me and I might not have bought them. I'm not convinced that it's fully organic as it also says 'Organic based'.

What do you think? Organic or fake?
