I signed up for Verizon 5 G wireless internet but decided that I no longer wanted to proceed. I cancelled the service and returned the devices within 30 days and I have a UPS tracking number. I received an invoice and called Verizon back on 12.6.24 and the associate assured me that my account was closed and at a Zero balance and the device was received. I then started getting more invoices saying I had an outstanding balance. I called again on 4.4.25 and spent over an hour and a half on the phone with several associates that kept transferring me to different departments. Eventually the associate hung up on me. I called back again spent over thirty minutes talking to another associate and I requested to speak to a manager or supervisor someone who could help me clear up this issue. I was transferred to another associate who was not a supervisor and was extremely rude. Had no empathy and interest in helping me resolve my issue and decided to disconnect me. His name was Ken and he refused to give me an additional information. I'm now calling Verizon again right now to try resolve this issue but I keep getting placed on hold and I've spent over 3 hours today alone to try to resolve this but all of their associates either transfer me to someone who cannot help or have no interest in helping. This is absolutely infuriating and by far the worst customer service I've ever encountered with any company.
