[2019] Mod please help

I have purchased membership for my alt account, the method I used was mobile payment. I have done this before and it's worked fine. I have bought bonds before on my main using my mobile and jagex use a service called boku? Now here is the problem; I've logged in on the main home page using my alts details and gone to purchase membership, I have then done this on my phone and tried to log in and it says no membership, so I log out my main and see I've been credited 30 days and think ah stupid me I've logged in the wrong account I'll just bite the bullet and do it again. I do it again ensuring I have the right details entered and low and behold still no membership, ah but another 30 days credited to my main. I can only assume the mobile service jagex are using save account details as well? I would seriously appreciate it if you could credit my alt with 60 days and remove them from my main as I cant be arsed spending even more money If a mod could inbox me I'd be greatly appreciative
