I am Customer

The customer has recently changed to another company but is blaming us because he thinks his website doesn’t look like it should. The following is his email.(And yes, he literally signs it as “Customer”)

Dear Sir.

You said: The domain appears to have been successfully transferred to eNom Inc.
and the site appears to be hosting with [other hosting co.].
Why does this domain still work in [hosting co.] ?
Please you use web IE browser or firefox to check this domain [customer’s domain] and then you know.
