Today was the worst experience I've had in a concert, my tickets were duplicated, I started the concert and the seats were already occupied, three of the ushers checked the tickets of the people there and they were the same tickets as mine. , reason why they did not stop immediately from there, they took me up according to the manager and they offered me better places but there were already 4 songs of the concert and they had me stop for 20 min with popcorn and coca in hand that better pull in the trash, I did not accept the offer because I wanted to withdraw from the place and requested reimbursement, seeing my refusal and being out of the stage area, arguing with one of the managers suddenly tell me: Madam your places are already vacated ... I demanded my refund and I was not in the mood to be in the place, but they told me there are their places only the other people were wrong. What people might hate the most is that they underestimate their intelligence, because what these people did was to offer other people the same thing as my best places and while they were quiet and in good spirits the offer was excellent, bravo for them Finally, these companies train their employees to be cynical and arbitrary and thus treat the clients of those who live.
Conclusion who gets angry loses and those who earn the most are those who have more because what can be done before these abuses?
She still tells me an attendant ... If I had arrived early this would not have happened ... No chi ... Now it turns out that I buy a numbered ticket and I have to get there first so that they do not win ... Totally mocked!
