Sorry for phone format in advance! TLDR at bottom.
I work at a phone carrier call center as customer service rep, we are technically tier one tech support so we still get troubleshooting calls. This was my call of the day for sure. Customer will be YM for yelling man.
Me: Thank you for calling-
YM: MY PHONE ISN’T WORKING!
Me: I am sorry about that, let’s get into the account and-
YM: MY PHONE IS NOT WORKING AREN’T YOU LISTENING?!
Me: I am listening. Again, I am sorry to hear that, but let’s get this fixed, what is the pin-“
YM: MY PHONE ISN’T WORKING! I NEED MY PHONE!
Me: SIR! What is your account pin? That way I can at least see-
YM: yells the numbers at me
For the next couple of minutes I am trying to ask him how his phone is not working, and he just keeps repeating how ridiculous it is that he can’t use his phone. Finally I cut him off.
Me: I am trying to help you, so if you could, answer my questions. What are you unable to do?
YM: NOTHING! I CANNOT CALL OR TEXT OR ANYTHING!
Me: Okay, at the top of your screen, are there any bars?
YM: NO! NOT A SINGLE ONE!
Me: Okay, drag down from the top of the screen, in that first box do you see a green bubble?
YM: NO! ALL GRAY! WHY WOULD I BE LOOKING FOR A GREEN BUBBLE?!
Me: smiling Tap the antenna to the right of the airplane.
There’s silence, and then I hear a ton of notifications come through the phone.
Me: It sounds like you have service! You had your cellular data turned off, so that’s why- click
I hope he felt as embarrassed as I felt successful.
TL;DR: Customer calls in because phone doesn’t work, turns out he turned his own cellular data off.
