Verizon Wireless Overbilling and Poor to No Customer Service Fort Myers, Florida

  I have been a loyal verizon wireless customer since 2013. I opened four cell phone lines with this company and they have not given any incentives. The service has been poor. We have not been able to make calls nor receive calls many times. My two year contract ended with Verizon Wireless in February 2015 and at this time they over billed my account. I have been in communication with them and they have not adjusted my bill. Verizon wireless has sent my account to the CBE group and I have also contacted them to dispute it. Verizon wireless has lied to the CBE group claiming that they have been trying to contact me, this is not true, I have been calling and sending them letters by certified mail. Please assist me with this problem because Verizon wireless is trying to cause difficulties.
