Verizon – Cell phone number

Hello. I don't know if this complaint will change anything but out of the blue my child phone number was connected to someone else number (a landline number) so I was calling my child phone and a lady answer I hung up called again then her husband answer the phone. I was so scared thinking someone took my child or stole her phone, the husband's and I went back and forward before we realized that somehow my child number was connected to his landline number we dont know how. So today [protected] I called total wireless/Verizon to see what's the problem and why were the two different numbers connected. They fix the situation and they placed the blame on me saying I was calling the wrong number, I know my child number plus my sister and her cousins were also calling her number, total wireless/Verizon dosen't care about their customers they were super rude to me didn't care how stressful it was for me to think something happen to my child they were very unprofessional, I asked to talk to someone higher and they told me unfortunately they doesn't have a complaint department.
