Disappearing data

<p>I recharged with the amount I use in a month and 2 days later it had run out. I called to enquire and was asked the most ridiculous questions as if I'm illiterate and using a cellphone for the first time in my life. I was promised feedback which never came. I called the next day to log a query and again was promised feedback withing 24 hours which did not happen. In the meantime I was told that I had subscribed to something a year ago and to unsubscribe I may not recharge anything within 72 hours, cutting me off from the world. Can someone get a clue? And how do I know my data won't just disappear again?</p>
