blank documents to be signed - no information

I am trying to desperate get my claim sorted. <br> I called for follow ups but are never able to speak to the correct appointed consultant<br> I can not get correct information.<br> I am now asked about cell phone records - LEGALLY NO BLANK FORMS MUST BE SIGNED<br> . <br> <br> currently my best interest are not taken as a customer.<br> <br> it look like this is causing a delay on my claim that is really not fair.
