Swissport International review: Ground check in (boarding) personal

Dear Sir/Madam
I'm disgusted by the behavior of Swisssport personal in Berlin airport.
I'm referring about a persons dedicated to admitting on board the passenger of flight Ryanair FR3311 from BER to BGY on Oct 21th, 2024 schedule departure at 17'25.
Those two men blocked me and imposed me to pay the 60€ because, in their opinion, my backpack was too big (I had a ticket including backpack AND 10kg hand luggage).
Both them did not check properly the size and the shape of my luggage and refused to answer my question how to solve the problem and refused to give me their name or registration number.
The flight above mentioned was my 111 flight in 2024 only and this behavior is unacceptable especially considering that I had exactly the same luggage in the two previous flights both with Ryanair.
I don't have to specify that bothy bags perfectly fitted on board either under the seat and on the overhead compartment.
Also the ground personal MUST have identification tags with name and pics as in all civilized front desk work.
I'm confident to receive your explanation and consideration about all barbarian uncivilized unacceptable rude disgusting behavior.
I will fill same complain using any possible social media (my secretary loves this kind of task).

Luigi Bertini
