Today I was reading article on Lithuanian press about customer of Mistertango who lost €500. Shortly, he lost his Mistertango debit card. It's possible to block card using Mistertango app, but for some reason he wasn't able to do that. He tried to contact support about this issue, but he didn't got answer. As written in article, it was contactless card and it don't require to enter PIN code when you spent up to €25 at once. So, person who found that card spent almost all money eventually. Good thing that Mistertango will cover these €500 and it will be returned to customer account. But one question came to my mind - when did Mistertango started to issue contactless cards? I can't find information about it anywhere.
And Mistertango said that have problems to answer support tickets in time due to fast increasing number of users. It can take more than week to get ticket answered.
