Cust: I'm the mother of X Y (Completely unknown person)
Me: How can i help you? (Thinking: " who the hell is your son??")
Cust: My phone is black
Me: Did you try to turn it on?
Cust: NO! when i call it's black!
Me: You mean when you try to make a phone call your screen go black?
Cust: NO! I can't receive calls!
Me: Can you please show how you make a phone call?
Cust: I say i can't call i have no money! (Already want to strangle her..)
Me: Well then it's easy madam you just need to put some more money!
Cust: But my son take care of everything!
Me: Then tell your son you finish all your money!
Cust: But i need my phone NOW! (i lost my patience NOW!)
Me: Then you need to recharge NOW without your son!
Cust: No no no... i can't do this without my son! But you know my son is X Y!
Me: Anyway you still have to put money...
Cust: But why do i need to recharge? (i know i should have bought that crocodile's pit for customer like this one..)
Me: Because you have no money!
