I worked for a company from around 2013 to 2015 and had a pension with around £8,000 in the pot.

I left the company when my father died and went home to look after my mother. I would point out I had the same email address from 2009 to the current date.

When Covid hit I had some time to chase up pensions and asked my former employer for nearly a year where my contributions were.

I received an email which in effect said I have lost the pension

I didn’t know you could lose a pension and haven’t with all my other providers, some going back 30 years, so I am confused as to why this is allowed to happen and would be grateful for any advice you can give.
