Supporting evidence for missing PRSI contributions

Did you make any pension contributions to a scheme operated by the employer during the missing period? If so, would you have any details of the fund that could provide you with an historical statement?

Thanks. There was a PRSA alright and I can probably dig out details of that but I'm not sure that it really helps with the question about "missing" PRSI contributions? I have plenty of documentary evidence that I worked for the companies in question and payslips or other evidence of payroll figures which I would have thought was sufficient. It's a little unclear what else DSP are asking for and the company name change may also be confusing things at their end. I'll see what I get in response to my latest email with some additional info.
