metall walking stick (Seaford BN25)

I had my NHS walking stick taken from my shopping trolley in Lidl, it was a shock because I need two sticks to walk . when I can hold on to the trolley then I only need one.
please perhaps someone has a stick which I can adjust to my Hight,
I only can collect from Seaford and Newhaven,
if someone can help please mail and leave Telephone No thank you
