A babysitter for a 6-month-old named Brandon Alex saw he had fallen and was unconscious. She called 911, but didn't get an answer. She called again. And again. She never got an answer.
Meanwhile, city officials said dispatchers returned all of her calls. But they never reached her. At one point, she was on hold for more than half an hour, Alex's mother Bridget said.
Bridget rushed home and drove him to the hospital. But he died on Saturday. And Dallas officials are investigating what went wrong, KTVT reports.
I just want y'all to tell me, why didn't you respond to my son? That's all I want to know.
On Saturday night, 911 callers in the area were on hold for an average of 30 to 40 minutes. The city's goal is to answer all 911 calls within 10 seconds.
The city said "ghost calls" from T-Mobile phones were to blame. When someone dialed 911 on a T-Mobile phone, it triggered multiple calls, flooding phone lines.
It is outrageous that T-Mobile still has not resolved the ghost call issue that is putting Dallasites in danger by clogging our 911 system.
Bridget Alex said she was attending a funeral when she got the call from Brandon's babysitter and drove home.
T-Mobile did not respond to CNN's request for comment (KTVT is a CNN affiliate.)
Issue has been resolved that affected some calls to 911 from wireless customers. We apologize to those who were affected.— AT&T (@ATT) March 9, 2017
AT&T tweeted it also experienced 911 issues last week, but promptly fixed them.
The Dallas Morning News reported a 52-year-old man, Brian Cross, also died last week. His husband, David Taffet, was unable to reach 911 for 20 minutes. Cross died in the hospital.
The Morning News reported T-Mobile executives said the problem was "unique to Dallas," but didn't have a solution. T-Mobile engineers flew into the city Wednesday to attempt to find solutions.
The ghost calls affect non-T-Mobile customers, since all 911 lines are affected. Taffet has Cricket Wireless.
