Looking for recommendations for another carrier that works well in Southern California. I went into a Verizon store today to see how my account used 6GB of data in 4 days while hooked up to wifi. Found an old phone number still connected to my account and the data the current owner of that number was using was being attached to my account. Easy fix, they just don't fix those issues in store, so I spent 40 minutes on the phone with Verizon support while still standing in their retail store. The customer care rep deleted that old number but tells me they are not willing to credit me back the data they can see was used on that line. My only option is to upgrade, pay for more data so I have some left this month. WTF?! You can see someone stole the data, you cancelled it but won't credit me back? Time to leave.
