My SIM card got deactivated for some reason after a while of being in Germany. Now, in NL, I have tried to reach customer service several times using all the numbers they provide, and it has been impossible to reach a human being to state my problems. No robot has yet been useful. The web, as well as the customer service, as far as I am concerned, is pure garbage. Lebara offers a very easy prepaid option, but pray so that you never encounter any problem and need support. Would never recommend.
