What a week~~!

How suay can i be...
1st my office comp crashed after a black out.
Then yesterday night, i could not call out. I can surf the net, send/rec sms, rec calls but i just cant make phone calls out using the iphone. Hub was facing the same problem, called CS and was told it was a net work problem. Hours later, hub's phone was bac in working status. But I was still facing the same porblem. So hub gave them a call and was told they are still solving the problem.
Woke up this morning, tried to phone calls and still NO. Called CS and was told SIM card might be faulty, just go to a HELLO shop to get it replaced. Went to Bugis, CS swopped his sim card with mine. End up, its the phone and not the SIM. He suggested that i go to Comcentre instead as there is a specilized counter for iPhone. And so another trip down town. And guess what.... it was merely a software conflict and all he took was 15 mins to restore phone to default. ARGH
Really mad right now...dammit
