I have been using it for almost 2years now. I have been paying to the same account number from my one(same) Account number. Suddenly they suspended my wifi saying i didn't pay. Sp after calling them for over an hour of holding and hanging up to call again. I was told that i will be called back but noone called back. Then i was told that my payment shows however they haven't allocated the funds. It's been over a week since i have been without wifi.
