Why does the new lollipop version keep on installing on my mobile?

[AC Question]

I looked at my mobile this morning and it was asking me to give the go-ahead to install/upgrade to the new lollipop version.
I gave it the ok and it installed successfully.
It then downloaded again and again asked to be installed.
I again gave it the go-ahead and it installed successfully.
Would you believe it? It then downloaded again and asked to be installed.
Will it ever stop?
If not, can anyone tell me how to stop it please?
I am on the EE network.
Thanks

There's the initial Lollipop update 5.0, and then 2 after that, 5.01 and 5.02....are you sure it wasn't just getting them all?
