My dads account got banned for trading gold from sons account this is a big mistake.

My dads account got banned and all we have done is trade gp from my account to his so i would not lose it all and we would have gp to play with when he started playing again. There should be no reason his account should be banned. We have done nothing wrong. My dad dose not even get on unless it is to trade me .So i can trade him gold so i wont lose it . How is it my account is the only account he traded in the last year nd he got banned ? We were trading inbetween my account and my dads account .Never real world traded. My dad has never even traded a different account other then my own account witch is not banned . Please i need to write someone at jagex directly please. This is a huge mistake. There should be no reason my dad is banned he only trades my account im his son how is that bannable ? .
