Trying to find old workplace pension

Hi guys
I'm trying to find a workplace pension I had way back in the early 2000s. I tried to use the government's pension finding tool but it only came up with a phone number for NEST. When I phoned them it became clear that I had to be a member, which I'm not. I've asked my old workplace which pension provider we used but they won't respond. Does anyone have any idea how I go about finding my old pension? I've moved house and bank since I worked there. Are my ex employers legally obliged to tell me? 
Thanks in advance.

Steve.

Not sure if they are legally obliged but I do not see any reason why they can not just tell you the name of the provider at the time. Are you sure it was a DC pension and not a DB/final salary/occupational scheme?
Who did you ask at the employer - HR?
Do you not have old colleagues you could contact ?

Thanks for your reply, it was a DC pension and it's a small company with just a generic general.enquiries email address with one secretary. I didn't leave on good terms, there was an awful clique in the workplace and I had a rant and they fired me and I took them to tribunal and won lol so sour grapes may be at play.
