Restons Solicitors Limited for Cabot Financial (UK) Limited for Hitachi Nova

I have recently received a claim (Restons Solicitors Limited for Cabot Financial (UK) Limited for Hitachi Nova). I have filed that I intend defending and have forwarded a CPR 31.13 request. Today I have received a reply from Restons effectively denying the request. I would appreciate any assistance anyone can offer, is there a paid service where someone can help deal with this on my behalf? Any help appreciated. Thanks
