Give me 24 hours (1 Days) and I will Unfollow 400 Twitter users that haven't Followed you back. For starters I need your pass and username. You can change this information after the job is completed. I will not alter, modify or change anything in your account. I will start Unfollowing your oldest Follows first. If you have more Follows than Followers Twitter will take your Following privilege away!
Following too many unimportant people can actually hurt your brand and undermine your organisation's image.
No Refunds!
