Disgraceful attitude of airline staff

Mango airlines has no respect for the elderly, my parents with medical problems were refused passage on their airline despite being at the check in counter 40-50 minutes before departure. The check in counter staff refused to try to accommodate them in any way. They blankly said they could not accommodate the luggage, then when we agreed to leave the baggage behind they changed their minds once again refused to allow them to board the aircraft. My parent of 86 years of age was turned away from the flight irrespective of explaining that my dad needed to be seen by the specialist the next morning and really needed to be on the flight. There was still 40 minutes before the flight departed and the lack of professionalism was evident when the staff looked so blank as if they did not have one ounce of energy to get up from the chairs they slumped on, Several of the staff just sat back and felt it was amusing to treat old helpless people in this way. Their attitude and lack of commitment to the public is shameful and brings disgrace to the airline they work for. This is what senior citizens have to encounter, people have no respect or courtesy for the elderly in the community. Furthermore, my dad was hospitalized and discharged 3 days ago on treatment for cardiac failure and also has an implanted pacemaker. The staff at the check in counter shooed us away to go and change the flight to another day in an attempt to get rid of us for "disturbing them" but failed to mention that there would be a penalty of R900 to change the ticket details. There is no drive, tenacity, urgency or common courtesy displayed by this airline staff and brings utter disgrace to anyone associated with the company! The "service" is dismal and goes far beyond pathetic! The person that called herself the supervisor was arrogant and had nothing to offer, she looked sleepy and disorientated as she went about saying she could not assist. A business that is so inflexible in exceptional cases especially where the health and age of the passenger is compromised clearly depicts that the company does not value its customers!
