They've managed to convince people to pay $800 (usually with some discounts to be fair) for what's essentially a $400-450 mid range phone. Even if nothing was defective and customer service was "perfect", it's still a midrange phone priced like a flagship.
To be fair, how would they even verify this? Unless it's outright broken (eg. no cell reception), someone with a "defective modem" is basically indistinguishable from the 99 other people with a perfectly fine phone, but nonetheless want their phone replaced for various nonspecific issues about cell reception.
I went to redeem my compensation - free battery replacement unavailable in your country, $100 credit unavailable in your country. I guess I'll take the $50 cash...? I fill in the form with my IMEI, full name, address, etc etc. After a week they send a response saying unfortunately after thoroughly looking into my case, I'm not eligible, and no further explanation is offered as to why. In effect it's as if they hacked into my phone and installed a virus that cripples the battery and there's nothing I can do about it, like this is just a normal way to do business now. You don't really own your phone after all...
