Had this issue with Pan F and FP4+.
e-mail response from Ilford:
"Based on the description you’ve given, and from seeing your image - the unfortunate findings on your FP4+ roll film links to the issue we raised on our website. ie our statement posted 02/03/20 -

So we definitely will be posting out replacement films to you. Though we will try our best to do this asap, it may take 2-3 weeks before you receive them. (I appreciate however, that replacement items don’t take away the disappointment of losing images).
In order to better help us too, however – please can you let me have the series of 4 numbers on the processed films lower signed edge?
Our company takes great pride in the quality and consistency of its products and all complaints are thoroughly investigated. I will be forwarding your unfortunate incident to our priority teams colleagues.
Please accept our apologies for the disappointment caused on this occasion."
