Please correct these lines.

I have been working as a sales and service executive person in NEO Medy Systems at Hyderabad since yesterday. I'm feeling comfortable here. I'm learning about sales right now and later on I will learn about service.  They will send me to Chennai for learning service.  I'm eagerly waiting for this.  Thank you.

Quick thing: Why is this in the Telugu section?  I believe this should have been in the English section.  Also some comments: "I'm" is written with an apostrophe like that, not whatever you were using before. Make sure to capitalize letters.  Otherwise, very good :)
