Bad condition of plane, call centres lie etc

Had numerous problems on our flights from SA to UK & then to Orlando as well as on return flights. Put in complaint on the flight via the hostesses Ipad & also complained to Heathrow ground staff but after 1 week phoned to find status of complaint and was pushed around from pillar to post. Promised a response within 5 days and it has now been another 7 days and still no response.<br> <br> I had also tried to complain while I was still in my holiday and had problems with online check in. Call centres first said technical error and said must call back after about 4 hours. 9 hours later was still a problem but then when phoned call centre they then said \port authorities had closed online check in"which was ******* as it allowed 1 out of my 4 pax to be checked in online. Worst is that allowed me to check in a 7 year old and not the adults?? Call centre clearly clueless or lying. Phoned the US complaints line while in Orlando and after 20 minutes (on the dot) it cut my call without even having an agents assist in these 20 minutes. <br> <br> Seems like they need a complaint line to deal with complaints about their complaint line? Even as a \""silver\"" class \""Loyalty\"" member you get no help?"""
