My mother is disabled. We were travelling back to London from Dubai on Tuesday 3rd September on the 1.30am flight with British Airways. A wheelchair was booked from UK on our travel to Dubai on 26th August 2019. We reached Dubai airport on 2nd September 2019 at 9pm as we had VAT to do. Our check in time was 10pm on Monday 2nd September as our flight was at 1.30am morning Tuesday 3rd September 2019. The check in counter did not open till 10pm on Monday 2nd September 2019. I went to special assistance to ask for a wheelchair as there was still one hour before the British Airways check in counter opened. The lady in the special assistance was very rude, she refused to give me a wheelchair, the staff member's name was Ms Hanan- Special Handling Agent, she was so rude, she told me that if my mother wanted to sit, then she could sit on the sofa which I explained was too low. There was also an indian lady sitting in the special assistance next to Ms Hanan, and this indian lady did not even acknowledge me as I stood there waiting for someone to help me, as Ms Hanan was on the phone to someone, this indian lady was too busy on her what's app instead of acknowledging me and trying help me. Here in the UK people are not allowed to use mobile phones for there personal use when on duty, but this indian lady was so engrossed in her what's app. I am very disgusted with the level of care and service received from DNATA staff. A gentleman named Cherian helped me, he told me that Ms Hanan should have called for authorisation for relesing a wheelchair earlier than normal. My mother had to stand for one hour with very bad leg pain, she has severe osteo artheritis, and a ruptured bakers cyst behind her knee. She has been given instructions by her Doctor that she is not allowed to stand for more than 10 minutes, but Ms Hanan was refusing to understand my mothers situation. She was not helpful at all, what kind of staff are DNATA hiring? I would like this matter looked into and investigated further. Terrible service. Please acknowledge me on this matter and steps taken.
