LATAM Airlines complaint: Baggage fee and delayed flight

My Terrible LATAM Travel Experience Returning from Rio de Janeiro, Brazil to Miami, United States of America
Upon arriving at the international airport in Rio de Janeiro, having checked in online, without having had the option to pay for luggage online, a latam employee at the check-in desk informed me that I should pay for the 2 bags that would be checked. I went to the payment desk and the Latam employee had the disrespect to make me wait for 30 minutes to tell me how much the fee would be. He told me it would be R$1,300 reais approximately $125 dollars per bag, totaling approximately $250 dollars. A theft!!! Absurd!!! Not finding the value of the luggage fee right, I paid it, but it is worth noting that on the way to Brazil, with a much more professional and respectful airline, I paid $35 per bag, totaling $70, instead of the “theft” of $250.
I went back to the check-in desk and it took approximately 1 hour when I was attended to check in my bags and print my boarding pass. A Latam employee left the service desk and went to another closed room, came back, did it several times. Absurd!!! Terrible lack of respect!!!
When it was close to the boarding time, the Latam employee said that they would not make the boarding at the scheduled time, as all passengers with carry on should dispatch the same. Terrible idea!!! Not caring about connecting passengers!!! There was a long delay in completing this process. When finished, we left Rio towards Santiago, Chile.
Arriving in Chile, I ran with my 6 year old son and my wife so we wouldn’t lose the connection. I arrived at the Latam connection desk and the employee informed me that I had missed it, there would be no way to catch that flight. As?! I arrived at the counter at 12:10am, flight departs at 12:30am. Surely I could take it, but the employee denied it and said that the bags wouldn’t have time to go on the flight. That I couldn’t pass the connecting gate, I should take a flight to Lima, Peru in the morning at 7:45am, I should wait at the airport for more than 7 hours. Detail that the Latam employee, very moody, didn’t even speak English, I had to unroll my Spanish. As an international Latam employee, she doesn’t speak English ???!!!! Or didn’t want to make any effort. There were 2 Latam employees in Chile, who said they didn’t speak English, or claimed they didn’t speak a single word.
As there was no other alternative, I took the boarding pass to Peru and then to the United States.
I went to the Latam VIP Lounge and the employee scanned my boarding pass, but he wouldn’t let me in. With all this, I still haven’t been able to feed and rest with my 6 year old son and wife.
We had to spend the 7 hours in the airport departures area. My son ended up sleeping on the icy floor of the airport, he was very tired. What a lack of respect from Latam!!! Unbelievable!!! Revolt!!! It even seems that we didn’t pay for the ticket, it is given for free, such neglect. It is worth mentioning that on the flight from Chile to Peru, the use of 2 masks or N95 was mandatory. Wearing a mask, no problem, but having to wear 2 masks???!!! Even being vaccinated!!!
I WILL NEVER TRAVEL THROUGH LATAM AND I RECOMMEND IT TO ANYONE!!! VERY LACK OF PROFESSIONALISM AND RESPECT TO THE TRAVELER!!! TICKET IS PAID BY US, WE DEMAND MORE RESPECT AND PROFESSIONALISM BY LATAM AND ITS EMPLOYEES!!! HORRIBLE EXPERIENCE LATAM EVER!!!
