I bought a small Gerbera plant a couple of weeks ago and they don't look like very well, this is the first plant I've gotten trying to make my condo look a bit greener and I'm worried.

When I took this picture one was so-so, today they are all loosing their petals but the pedicel (or stem?) is strong and steady.
They look like this today (But again, the pedicel is not twisted):

After getting them, I searched the recommendations and I bought a slightly larger and deeper vase and a premium potting mix called promix, I filled the vase with promix and dug a whole in the middle where I put the flowers with the soil it had from the beginning, watered it thoroughly and left it to drain in the sink for about half an hour until there was no more water running, after this I put it on top of a plate, to find one of them the very next day with their petals about to fall off. They are sitting inside my condo next to a window, it's cool inside (Normally under 23°C).
What am I doing wrong, what should I do more, what should I do less?
