Customer Address different to billing address

[longstockings]

Hi

I have a customer whose website uses checkout without account and Secure Hosting to take payments. He noticed that on a recent order the customers address and billing address were different.

The billing address should be the same as the customers address and I don't know how this has happened. Both addresses were the same apart from one of the numbers in the post code.

Any ideas how this could have happened?

That has nothing to do with "checkout without account". A customer will still be able to enter a different shipping and billing address
