No, the cal was about your ESA assessment but you have obviously heard.
Sending your ESA form will be of little if any value, you need to request a copy of the report that was produced, you can send this but you will need to explain why it is relevant your PIP claim, there are limited areas of overlap and even where there are, the criteria can still be different. Contact the DWP office dealing with your ESA claim.
