No customer service skills

Being a regular traveler , Lift had always been my go to until Tuesday morning with flight GE101. There was apparently a system error with seats allocation. While the system error was not necessarily a huge issue but the manner in which the airline member ( which later noticed was not part of the cabin crew we flew with, but a staff member of the airline) had handled it. She was rude, unapologetic showing no customers service skills. Lift should work on their customers skills or they will loose clients
