Store problem buying gametime more 1 account same creditcard

I bought 12 months in advance on my 1st account worked ok.

I bought 12 months in advance on my second account multiple times, it said the transaction was successful and gave me the old transaction ID from last year. I had to open LOTS of tickets. First time they refunded me. The second time same thing happened but now I have to wait 20 days to get my money back. Please look into this. Seems you cant buy gametime packages on more than 1 account with the same credit card.
