According to this map there are three Tesla superchargers in the Czech Republic:
As well as about a dozen destination chargers:

However what you might be missing is that Tesla's can also be charged at normal public charging points used by other EV's - both AC and Chademo DC with an adaptor cable. If you go to http://plugshare.com and look up Czech Republic you'll see there are over 30 DC rapid chargers (orange icon) and over 30 AC chargers (green icon) available which can be used by any EV's including Tesla's.
Finally don't forget that if you have off street parking you can charge any EV at your house. As Tesla's have a long range compared to most EV's its perfectly possible to charge only at home and not need to charge anywhere else unless you go on a long trip.
So it looks like there are plenty of places for a Tesla to charge in your country!
