Ufone Network Always Busy

At first I thought, its just me who is facing this problem or some issue with my handset but I confirmed it from my friends and they are all experiencing the difficultly in calling and even sending SMS. I am unable to call to the Customer Services to lodge my complaint.

I am having this issue from the last 36 hours. Signals are full but no connection. All I receive is the alert message “Error in Network Connection” and “Unknown Error”. Gosh!!!  my call is connected (feeling lucky), let me lodge the complaint and get back to you with updates.
