Unresolved Complaint

I’ve called customer care several times to resolve an issue and sent two emails to customer care. The first phone call resulted in me being hung up on and no one called me back, the second call they said my complaint was escalated and someone would call me back. The third call the supervisor was very rude and just put me on hold mid-sentence. I’ve been on hold for 15 minutes now and I don’t think he’s coming back (I’m on right now).  None of my emails were ever responded to. Terrible customer service. I wish I had never switched from Verizon. I spend $400 a month on phone, internet and TV and can’t even get them to address my issue.
