Can't pair a color bulb

I have a new bulb.
I plugged it, but my ios app wont connect, it’s stuck on 0%.
I deleted the app, reinstalled it, logged out, changed all servers, nothing.
It just won’t pair at all.
Is this thing even working for someone?

PS: i tried three different iphones. The app is stuck on 0%.
PPS: i resetted the bulb 3 times.

Can we get refounded for something that is not working at all?

For the connection issue, you can check by the following steps to see where the problem is:

1)Reset the lamp by power on and off fives times 5 times in a row, and then see if there’s AP named like “yeelink-light-***” in your phone’s wifi list? If yes, go to see Step 2; If no, it means there’s something wrong with the wifi module of your lamp;

2)In Yeelight/MiHome application, add the lamp you want to connect. Make sure there’s no special character of your router’s password. If the connection successes, congratulations, if not, go to Step 3;

3)See if the lamp in your router’s DHCP list, if yes, it means there’s something wrong with connection between your router and Mi cloud. Please have a check with your ISP if it blocks some domain of xiaomi. If there’s not the lamp in your router’s DHCP list, it means, the lamp has problems to connect to your router. So please have a check if your router block the lamp or your router has connected as more devices as it can connect.

So please have a check that which step do you stuck?
