I purchased SDI Card from SDICARD.com I spent two days to make a call. I bought two cards @ 2 dollars each. In website it showed 16minute for KTM and when called it said 10 minute. I talked a guy in Chat section, he told the numbers shown in website are true. He blamed me for not using the card correctly, I told him that in first trial, it told 10minute. Then, the guy in chat did not answer, he just neglected my questions, that clearly showed he knows the trend. Next day, I called a guy over telephone after struggle, he gave another set of new cards and they either did not pick my phone (checked the number or their line was too busy). The new card also did not work, the way the guy told. I finally caught him over phone, and he told me that he will try another number. He asked the phone number in nepal I was trying for. He sent me third set of card numbers. It also did not work as he promised and it was little less than 2 dollars i.e. 1.89 dollar valued and rest money to be credited in next purchage. ... Since it did not work, their telephone did not like my phone number I called SDIcard new york head office. Finally, I found the name of the guy in charge of phone cards and they gave me his hotline phone number. I caught him and told him that I am struggling to use his card. He promised to help me and fix the problem. He asked for some time and his guy called me and gave a 4.59dollar card and promised it should work for 58minutes to ktm. After spending more than 24 hours, I got 4.59dollar valued "Budget" card. I called Nepal, first time the line was disconnected after 10 minute talk and second time it worked for 35 minutes, thus totaling 45 minutes. It was still less than what they promised. So, you have to use a factor and have strenght to muscle with them, provided you have time. "Time" is important to those who work in hourly basis and these card companies know it, so they try to show bigger number while you buy, and blame on you when you complain that the number is not accoring to advertisement. ... Only way you can do get fair minute is to threaten them to dipute with credit card company. You need to keep the website 's ad page that showed the number of minutes and what happens over telephone discussions while your dispute with the telephone talks. Its better to have text chat so that you can produce it as proof. Like time is money for you, it will also be waste of time for them to answer the credit card company's questions on behalf of your disput. Do not buy using DEBIT card, debit card does not have that strenght against fraud as credit has. Debit card is a priviledge to you, credit card company get nothing from you, so they don't include in disput policies .... (I am not sure, but this is waht a friend who was in trouble told to me). Dispute it, whenever the number of minutes are practically less than that you assumed after applying some cunning factors in this capitalist world, where everyone is trying to cheat you and money is considered everything. Well, I did threatened these guys about disputing and in fact I disputed it with my American Express card, and their response was very good, and it costs nothing for you to dispute against those cunning guys who advertise something else and offer something that is quite below expectations. It will also train you how to dispute, show your anger and make requests and .... ask for justice. Learn it. As long as you are not deliberately trying to cheat the other guy, and your disputes are genuine, you don't have to worry here. If you are not trying to make a fraud dispute, but making a real genuine dispute, you will lose only time and effort at the most. Your dispute might benefit others incluidng yourself in next round of shopping. Good Luck. GP
