Failure to respond to Condition of WIll

I am dealing with a probate where the circumstances around the preparation of a WIll is in question, but not enough evidence to pursue this (just lots of circumstantial evidence). So the Executors are proceeding with the Will as it is.

It was sent to me by the company that stored it, even though it was homemade. The Probate Registry ahve raised questiosn about staple holes, etc., which I have directed to the Company twice by signed for post with no response. We could do with them responding officially.

The Probate registry has just said that I can reply to say that this is how I received it, and explain that I have written to the Company with no avail.

Can I or the PR compel them to respond? What are the repercussions for them not responding?

Or do I just need to bite my tongue and proceed as suggested by the probate registry?

Thanks

There is a provision allowing you to question at court people who have knowledge of a will: Senior Courts Act 1981 . The other alternative seems to be a sternly worded letter. Calling the company would also make sense.
