how to get my ipaq sreen repaired by warranty

On 6th August my ipaq 5455 screen turned white and nothing can be done.
The ipaq works well but nothing is shown in the display.

I opened a case with HP and the told me they'll take my ipaq to service
the following day.
I'm still waiting for them. I have called them everyday since 6th August
and I always receive the same response:"We will take it tomorrow"

I have sent three complaints thru website a 1 by phone and nobody calls
me. (sometimes i check if my phone is working like a young loved guy does
while
waiting for her girldfriend call)

Last week I explain my problem here but my message dissapeared and I was
banned from this forum. (I didn't use bad language)

does ne1 here know how to solve my ipaq screen problem or how to do HP to
take my little ipaq?

Please help me!
