Today happens to be my first day at work, so before we start the work properly we have to undergo some training so that we will have full knowledge of how the company is being run.

Congratulations on your new job. It's a good thing that you were trae on one of this very important topic "customer service". I trust that with the things you learnt, you will be able to handle customers well and be able to deal with any issue that may arise. Kudos.
