What a terrible Flight!

Actually a day before my flight I tried to online check-in and apparently I found my second flight (the first one was from Harare to Dubai and the second one Dubai to Tehran) has about 8.30 hrs transit which was supposed to be 1 hr and something... I just sent a message to the agent which I bought a ticket from and they didn't even know! I mean less than 24 hrs before my flight they didn't let me know and If I didn't want to choose my seat online I would not know till the flight Time. Apparently Emirates Airlines canceled that flight totally so I had two ways! change my flight day or stay about 9 hrs in the airport!!! I mean no respect for your time!!! And the other point is I bought an expensive ticket to not stay long at the airport! The last thing Agent could do for me was changing the Airline from Dubai to Tehran which was the cheapest flight, Fly Dubai. at the end, I had 6 hrs of Transit which made the end of my trip terrible. And Also During the flight from Harare to Tehran, I couldn't find a suitable place and I was sitting next to a lady whose chair was so tiny for her and she was almost sitting on me! So when I found some seats are empty I asked Stewardess to change my seat and the answer was you have to pay extra money!!! What a surprise... almost 10 hrs flight I was standing all the time and I couldn't sit even properly not even sleep...

I really expect Emirates to Say a big apology to me after a tragedy they made for me!
