i will have to dig out the letters to see if they claim to own the debt. do these dca's ever actually take it to court though?

Ive been getting harrased by scotscall (calls, texts, letters) for a debt allegedly owed to david lloyd lesuire, they say i didnt give 3 months notice, i say that i did. they keep threatening court action, i keep telling them to go ahead, just tell me when i need to be in court. are they likely to actually take this to court? the debt is about £350 so hardly worth it?
