Where is my Will?

In October 2014 I completed the online will application. Everything seemed very efficient and shortly afterwards a courier came to fetch the documents. Since then I have heard nothing. The telephone number given in the correspondence does not work, emails are ignored. What I want to know is whether the will I sent in is valid? Has it been received? Did all the documents satisfy legal requirements? Why have I not been billed for the so-called \safekeeping"? These are important questions as I need to know if I should go to a proper professional instead."""
