I'm 99% convinced they purposely try to avoid unlocking accounts for as long as they possibly can.  After failing to respond for so long they asked for the same ID photo they asked for earlier with no reasonable explanation as for why the other one wasn't good enough.  They didn't even make it clear whether they are denying receiving it (I'm sure they received it) or they are just trying to nitpick some minor detail.  It is common for them to ask for the same things they've already received over and over again.  This is a uniquely horrible company.
