No response to written complaint
1K Premier on United, flew SAA a few months ago. There were some major issues, including no workable headsets for the 18 hrs flight and FA flipping out and being verbally abusive. We emailed a complaint letter to SAA, but after the automatic acknowledgement (30 days for response, 60 if investigation required), have never received a reply. Nobody answers at the US customer service phone line.
Is there any other recourse, e.g. contacting StarAlliance or United, or filing a complaint with the FAA? Or do we just forget it? Sounds like SAA has more problems than dealing with one or two upset passengers.
