Broken new screen, how do I deal with this?

Hello,

Last month I ordered and received a new screen/digitizer for my iPhone XR max. Installation was easy and the phone was back on-line in half ah hour. Not for long unfortunately. A week after the replacement, the digitizer became irresponsive. I had to let the battery die and subsequently reboot my phone.

It fixed the problem for one day. Then the digitizer froze up again. I decided I was going to open the phone to check the ribbon cables for faulty connection. Alas, when opening the iPhone,one of the cables between the screen and the main board tore.

I resorted to re-installing my old cracked screen that now has been working flawlessly for one week.

Is there a fix for the broken ribbon cable, or can I return the screen for credit or repair?

Thanks,

Maurice
