hello, I tried to buy credits by sending a text message with PASS flagged to 81027, the message is sent (and charged as a normal text message). But right after I receive a text saying "technical error we could not process your request blah blah blah blah and the 1.50€ will not be charged" (fortunately by the way ^^). I would like to know if it comes from me, from my phone, from the site, from the "bank"... Who has ever had this problem?
