Personally i have never had issues with bitify when purchasing so i can't vouch for how legit or responsive their support system is because every single purchase just goes through seamlessly. But i can say for sure that their deposits and withdrawals system function very well and that's a good sign for a well run business.

They're one of the leading bitcoin escrow sites as well, you can use them with confidence.

As long as you make sure that the goods you receive are legit and not reversible, you are good to go.
