In Credit Somehow?

Dezeaz

Hi all,
I have a strange one if anyone can help me please.
I have a virgin money card and the balance as of a couple of weeks ago was roughly £1250.
I made a balance transfer from my mint card for £900 (18th Apr). This showed up on my mint card a week later, and appeared on my virgin online statement. Now showing an outstanding balance of roughly £350.
On the 26th of Apr i made another balance transfer from the same mint card to clear the virgin balance. This showed up on my mint card soon after, and i have been waiting for it to show up on my virgin card. As i logged on today i noticed my account was in credit , roughly £900?
And i'm not quite sure how. Only the 900 and 350 payments are showing on my statement online?
Online the £900 transaction date is shown as 18/04 but the posting date is the same as the 2nd payment.

18/04/2008 01/05/2008 PAYMENT - THANK YOU £900.00 CR
01/05/2008 01/05/2008 0602 PAYMENT - THANK YOU £350.00 CR
I called virgin and they only see the 2 payments above, but somehow i'm in credit by almost 900.
I cant check my mint card at the minute as i havent got my log on details with me, but it does seem a bit strange.


Update - My mint card is only showing the 2 transactions as well
