They didn't help in any way, they sent them to the supermarket, they sent them back there, then they sent them to the mobile equipment store. If you are a tourist with a du tourist SIM card, then nothing will help you here. In any case, you need to pay with a bank card, if you don't have one, then you can only ask someone you know to pay for you online. The tourist SIM card is valid for free for only 1 day
