Thank you so much for your reply.
I completely agree with everything you say,
however I do apologise and must add that I hadn't updated them with my new address, which I moved into early December 2017,
(CCJ issued in February) so technically it's my fault and not theirs, right?
I only found out when I checked my credit file and saw the CCJ had been issued.
It is unfortunate the court papers and house move coincided with each other, but still I should have updated them beforehand I guess.
This may change your opinion and I'm sorry for not making that clearer.
This,
