I'm going through the same thing right now. My outbound miles were credited. Return miles also out of DFW were not. Got the runaround on the website, and on whatsapp. Whatsapp gave me the form to fill out, I submitted it and they emailed me back asking for the same info I already emailed to them. That was 2 days ago and no reply. It's been over 1 hour since their last response on twitter now when they said "be back shortly"
