How do i reset my account to start fresh?

I had an employee working on my Ad Words account and I fired him. I do not know what he has done and I want to start fresh and go through the entire process from the beginning so I can learn. How do i do this? I also have a $75 coupon and how do I apply this? thanks

 

Simply create a new campaign. Delete the old one(s) if you want. Those coupons by the way are good only for new accounts, usually 14 days or less.

 

just get a new credit/debit card, a new gmail, and restart.

 

Well, if you want to use coupon for your advertisement, you must create a new account with a new gmail, new credit card. Old account can not use coupons.

 

Close your current account as it may have a negative keyword history. You can do this on the billing pages, there is an option to close account. Once closed, then you can open another account.

 

With same credit card details?

 

I can't find the option to close my account. Are you sure it's there? I just opened my account yesterday.
