It's impossible to tell without seeing more context.

Suppose, I am talking about an airline. You should take its service or services.

Hi faisalkhan;

Nouns can be singular or plural. It all depends on what you want to say. It is one thing, or many things you are talking about?
eg.:

You should take its service from London to Paris.
You should use its services any time you fly.
