They delivered within a few days, but the followers only lasted for a couple of weeks. Then from 50k, they dropped to 20k and keep dropping. They do not respond to emails, and they do not have a phone number where you can call. Also, followers are not active users as they claim. Their followers are inactive accounts in East Asia. Do not waste your time or money with Instabilify. All these other reviews are probably fake.
Scam, scam, scam. I bought Instagram followers from the website www.instabilify.com. It was only waste of my money, ‘coz it was mentioned on the website that they would provide it within couple of hours, but they didn’t provide it at all. Their offers were the scam, so be aware and place your comments about this website and their offers. Please leave comments about your experience with this seller.
