They are really Scam. I bought a $5 phone card actually I paid $6 According to their list I could make phone call to Tehran for 2C per minute. After I first use I figure out they charged me 12C per minute. I call customer service about that issue, after almost 15 minute on hold I describe the problem for their Rep, he said there is problem and it going to be fixed for you within 1 hour, next day I try the phone card it was exactly like before I mean remaining minutes hadn't be changed, I call them again they said he's going to make a clime and send it to front office to fix the problem within 24 hours.. / after almost 30 hours nothing happened. for third time I call them he repeat every thing exactly like before but with more death time, 48 hours! I told him I'll sue your company, He replied me " It never gone Happen". Before i buy that phone card I search for them I found then on "wikipedia.com" that's why I trust them, now I'm pretty sure they wrote it by themselves to fake people. It was really bad experience that I had with them they charged me 4 more times. They sell phone card with several names that one I got was "JUST CALL".
