Dishonest handling of Estate documentation

Captial Legacy blocked mine and my Husbands email address when we queried how my Father-in-law signed his Last Will and Testament 2 days after his death. We requested a death certificate and were told that they are not mandated to speak to us and blocked us. Husband is a beneficiary on the original will. I believe a company would only do this if there was something to hid. A bit of a childish act from an apparent Established Professional company. Definitely appears to be foul play on their part and with their relationship with the Masters Office.
