Let me know please how you go
I replied to your question within 2 minutes of you posting it.
If you come to this web page and scroll up you will see. I'll even repeat it below for you
ok... but still confused why you said you got no reply when I repeated the instructions a few times...
But, if you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
