I subscribed to AIRTEL's unlimited blackberry service on my mobile. I like it because I'm always having something to do online and anytime I'm in Nigeria, I'm always permanently online with my airtel. I've never had any reason to complain until last week of course. I tried to make a call at night and noticed that I was down to nothing on airtime. Seriously, like 0.00 when I'm supposed to have at least 500 box. Thanks to my cousin, I found a way to borrow some money from airtel just to make the call. That is something I do not like. I do not like the word "borrowing" in whatever form it comes.
