Disgusting customer experience!

I am shocked by your lack of service and lack of concern for your customer's. My daughter has a back issue. She flew from Sweden to Doha yesterdayon the 16h45 flight. The power failed while attempting the first take off. They were first kept on the plane then.made to disembark and re embark before leaving 3 hours late. Most of the passengers missed their connecting flights. On arrival in Doha no hotel rooms provided. They had to sit and wait for the 08h45 flight this morning which has now been been chance to 12h45. She does not have pain meds as she only packed what she needed. 11 hour delay no hotel...sitting waiting for you to mess then around again. She is in huge pain due to clever plan of putting them on a 08h45 flight and then.movong it our again by 4 hours to avoid putting them up in a hotel. We always used to promote your brand to our friends and family but we are shocked....never ever again. Disgusting Qatar!
