Unethical business practice bad customer service

Yesterday  I had to speak to 5 different  people for the to get them to  understand  that the cable being put inside the home was not completed.  I had the worst customer service  it was unbelievable  that you have people  working their  that cant understand  what i was telling them.  The customer service  man siad for my present and past issues he would let me Have a free phone I only  had to pay for the tax and the service  once I activate the phone. Today I get a bill/ contract that I agree to pat for the phone. The custom service  lied about giving the phone for free.This is such bad representation  of your company moral conduct and business  ethics .. I hope that  so.one from complaints  or customer serives ethics departments  calls or provides some information    as I'm considering  legal action
