SD set aside now threat of ccj

Hi everyone, some interesting reading on here!  But I can't seem to find an answer to my problem with lowells. I won a set aside of a SD last year due to no cca and the account in dispute. Iv heard nothing from the low life's until now Iv had court papers threatening ccj? Can they do this? Any advice would be greatly appreciated. Thank you
