Cabot shoosmith debt

[Gilloolyt]

Hi. Took a bank loan 2006. Defaulted 2011. Shoosmith solicitors sent a sheriff court citation to attend court for the debt (Scotland). replied back saying it should be stat barred. They refused saying because they sent a citation a few months before the 5year mark then it’s still enforceable. So I asked them for copy of credit agreement etc and they took from March 2016 - dec 2019 to come back with the documents. *They are threatening legal action again. My question is will the court case still be open from 2016. And if it is can I go down the route of dismissal due to unfair delay due to the fact they raised the claim then took over 3 years to provide the evidence in my opinion a tactic to stop it becoming stat barred. ? Thanks*
