I have tried loading recharge card on various network, but it's plainly funny how these things works. I forgot, like totally forgot how to load my Etisalat simcard using the right code. Lolz, funny how it sounds now, but then, I didn't find it funny. Thanks anyways to the 9mobile recharge code method, it worked wonders and I was given an option of recharging via 4 different methods.
