AT&t instruct their Employees to LIE

I am filing a complaint about AT&T I have service with them for TV Phone and Internet. I called on 01-03-2018 about when my contract would expire. I spoke with Joshua *****, AT&T Loyalty Group. I was informed that if I returned 3 receivers my bill would be reduced and my new bill would be $59.00. I asked for a email confirmation about this conversation. I did not receive the email. I call in on 01-04-2018 and I speak with Richie employee # ***** so I was told as the conversation continued I asked to speak to his supervisor who REFUSED to get on the phone Alfred Employee # *****who has the SAME EMPLOYEE # has Gregg who finally got on the phone a continued to LIE about everything. When I questioned him about his employee # being the same he could not answer the question. I do not understand how the FCC allows this DECEPTIVE BUSINESS to operate like this. I only called in to check about my service and when it was going to end so I could adjust my service to fit my needs, What I have learned is that AT&T have employees that are instructed to LIE to customers from employee #s. I have NO Recourse but to stop paying this corrupt organization. Hopefully you will follow up on this complaint. I am sure I am not alone with the LYING that AT&T is allowed to do. To sum it up I was told if I returned 3 receivers my bill would be reduced to $59.00 from $89.00.[edited for privacy-please do not post personal or unique information such as but not limited to full names, employee ID numbers, email addresses, phone numbers, account numbers, etc.]
