We where very unfurtunated with My Space!!
By accident I cancelled my reservation....
I called right after the click!! They never anwered my messages, I called the ofice and someone told me that the person autorized to do it, was not in the office at the moment.
Then after more phone calls, waiting, texting... They explainned that their policies do not allow to fixed accidental cancelations.
At the end of the day, I had to book somewhere else and was charged for 2 days.
