Customers of telecom firms have been told to reclaim money owed to them when they switch contracts.
The regulator Ofcom says in the past two years about two million people have left at least £10m on their old accounts.
Typically the money is for line rental paid in advance, or promotional credits offered at the start of a contract.
Ofcom said its advice applied to mobile and landline phone services, broadband connections, and pay TV.

So now you know..I never did..
