Using trust wallet and ramp at 16

Hey. So I’m currently 16 and began by using ramp through trust to invest £15 into solana. Recently got some money and wanted to invest another £70 and upon doing this I was told I needed to verify my identity. No problem. Showed my passport and all that and it’s locked my account. I’ve only now been told I needed to be 18 however I have £15 worth that I can’t withdraw as it’s too little. What should I do here? Should I hold until I’m 18 then buy more or should I contact ramp and try to withdraw my £15? Ramp let me sign up originally to buy £15 and accepted I was 16 with no question. I’m a beginner to trading so please be nice.
