yesterday and the day before yesterday tried to make an appointment at 2 different companies.
A few hours later I got the excuse for the first one, I can't continue because something went wrong with the agenda. The second yesterday, again a few hours later, another excuse something went wrong with the agenda.
And if you complain you get to hear, well it can go wrong.
2 times ????
Never again through this company.
