Contact Trace App

I just received a text from the NHS about downloading a contract tracing app unfortunately I could not reply otherwise I would to have told the where to I cannot download apps anyway so that is a waste of time if I could I still wouldn't bother I don't remember giving them permission to contact me I remember during lockdown receiving a text about staying at home from the government how would they like it if I just sent them a text reminding them to do the same or if I said does this apply to Domini cummings and Neil Ferguson as well
