Out of the blue today, I received a letter from Writers' News. It had the wrong initials on it, a different Customer Reference Number and thanked me for subscribing to Writers Joint (no apostrophe). I'd never heard of Writers Joint.
When I telephoned the Subscription Processing Team, they told me that Writing Magazine/Writers' News have been renamed, and Customer Reference Numbers were changed some time ago (the old one is still appearing on my bank statement, though).
They agreed that they had loaded my initials wrongly.
