Vanquis balance transfer help!

Hey, if any one could help me out I'll be eternally grateful.

Short question:
Does anyone know of a credit card that will accept a balance transfer from a Vanquis and Ocean Finance card?

Long story:
I've been struggling the last few years to pay off my credit cards - 1 with Vanquis, 1 Capital One, 1 Ocean Finance (a subsidiary of Capital One). My sister kindly took a Sainsbury's balance transfer credit card, to transfer all debts over, I then pay her card off each month so reduce my payment and clear the debt as it's 0%interest for 3 years.

However, when we tried to transfer the balance, we were told that the Vanquis and Ocean Finance balance could not be transferred onto the Sainsbury's card - this is due to Sainsbury's banks rules, not a restriction with Vanquis or Ocean Finance. Luckily the Capital One balance was transferred without a hitch.

To work around this we are planning to transfer to another card that will accept balance transfers with Vanquis and Ocean finance.

Have any of you Money experts succesffully made a balance transfer from Vanquis or Ocean finance recently? and if so, who did you use?

Thanks in advance :A:A:A:A
