Hi all

Received a Letter Before Claim from Moorside this morning containing no detail and asking for £170 for an "unpaid invoice"

I sent them the template email asking for details etc and they replied via email with the below

They have already issued a Letter of Claim for the above on the 14 May 2025 for the same PCN but under under a completely different reference but the with same PCN number.
I responded to the Letter of Claim as per the advice here and heard nothing since

I know Moorside are clowns but do I need to respond in any way

Thanks in advance
