Etisalat Nigeria; a glutton

They won the heart of Nigeria students with the 15mb weekly service, they were one of the first few network that reduce the price of blackberry subscription. But these days, they have 40% of Nigerian in there pocket, maybe it's the reason for their poor customer service; I called their customer service for 40minutes and no one picked the call until I felt tired.
I went to there experience centre and wait for more than 2hours...what!
If you're to come and make money in our country, at least satisfy the customers, isn't that what market strategy meant?
for some of us that don't remember or don't know:
