SHOCKING SERVICE FROM ETIHAD

I contacted Etihad Airlines on 8 Jan. 2015 and informed them that my Mom, Sister and I weretravelling on Etihad Airlines from JHB/Abu Dhabi/Beirut. At Abu Dhabi we were told the flight had been cancelled and we had to fly Middle East Airlines. We did as we were told only to discover when we arrived at Beirut Airport<br> 14 Dec. 2014 that our baggage had not arrived. We were informed to return to the Airport the next day<br> to collect same as the baggage would only arrive on the next Etihad flight to Beirut. I informed them that we were not prepared to be penalized by having to pay for two taxi fares. Surely it was the onus of the airline to have our baggage delivered to us???? Besides having to travel back to the airport by taxi, we had to spend over 5 hours on the road back and forth. We furnished them with proof from Beirut Airport that our baggage had not arrived. They then requested that we furnish them with an invoice at which time they would pay the claim. One doesn't normally request an invoice unless one is travelling on business. We contacted the Taxi company in Beirut and they furnished us with an invoice. This was sent to Etihad over 3 weeks ago and they just ignored
