I recharged first time of DHS 20, but in three days it has been finished. i did only 2 to 3 calls, but that time i ignore this. After that, i recharged again of DHS 20, but this time again my balance is finished, even in one call. Third time, I recharged of DHS 50. I did one call of one minute and the balance showing of DHS 40. What is this? I am trying to call to the customer service, but there is only computer voice. How can i reach the customer service people? I want to talk to that people. Why my balance is going even in one call of one minute.
