Wells Cross Post 1710

The entire below is dated 11th March, and is believed to be from 1710 (a couple of other examples are known from 1709).  It has a rare "WELLS / X" cross-post handstamp, one of a series used for mail that was going on the Exeter - Bristol route without going via London.

The entire is from the same correspondence as other cross-post letters from  Croscombe to Plymouth.  This letter is asking why the correspondent hasn't had any reply.
