Address in the registration and check out

[help]

Hi,

Customers entering the address at the registration and after that they are entering the address for credit card at the check out.

Some customers addresses are different for the registration and credit card.

The problem is the address is changing for the registration information automatically if they give different address for the credit card.

Note: It should be different addresses because some customers shipping address and credit card addresses are different.

Please help on this and provide solution.

Thank you
