The 8th of January 2008, Iberia.com delivered two tickets for identical
flight (IB7164->IB6274->IB358 route), with identical trip dates
(departure 16 of February, turn 28 of February) and for the same traveler (Rafael Carrasco).
Apparently, Iberia will not return the money they charged twice just for one
service.

Mainly, two reasons created this conflict 1) the deficiencies in the iberia.com web,
which stopped showing any information about the first reservation (it simply, disappeared) and 2) the extremely unprofessional phone assistance service where they told me that the reservation was canceled and suggested me that I should create a new reservation (and then call to their headquarters in New York as the flight came from the US).

As a result, the new reservation was confirmed and the ticket delivered in less than 30 minutes (without any additional local nor distance call!). A few hours later, the ticket corresponding to the first reservation (4 days older, as it was issued on 4 of January) was delivered even if this reservation, according both to the web and to the telephone operator of iberia.com, was canceled.

However, iberia.com immediately charged on my credit card twice the amount of 660,69 euros

Since then (45 days and counting) I am unsuccesfully trying to obtain any information from iberia.com and about the extra 660,69 euros they charged
(last news, on the 10th of February were that they canceled the first one ticket and told me to wait for a reimbursement).

However, the barriers that Iberia has implemented with the only goal of preventing that customers can talk to somebody in the company who has any decision capacity (or, at least, any reliable information) has transformed the customer service into an inaccessible fortress. As one can even doubt that such a department exists or it is governed human beings at all, I will write about this adventure in the following blog's entry.
