Hi,
I appreciate your further information; and advised Christine call me to hear it last Friday.
This is not at all a clear sentence.
Do you mean you received this information in the past? Do you mean you appreciated it then, or you apprecaiate it now?
Did you advise Christine last Friday, or did you advise Christine (perhaps last Thursday) to call/hear last Friday?
You don't need a semi-colon.
Best wishes, Clive
