Test labels vary.
The shop are in the right to ask for more information if they are not sure on the test label.
When it was tested a certificate will also have been issued, you could contact SAS Ltd
The cylinder ought to be marked with the test date, tester and their Idest number
You sometimes get the blue Idest neck label accompanied by a label as in your picture

I see no SAS Ltd, but there is Safety Air Services of Southsea
However do note that your label is for June 2009. The law on testing changed on 1 July 2009

Scuba related and there are different test / time requirements but this is kind of relevant:
