Cox, this is embarrassing!

I signed up a month ago. My bill is already due and I still do not receive the service I'm paying for.

This whole process is being a huge mess. let's break down:

1) The promotional price on the website is a blatant lie. Try it yourself, and make to checkout page. You will never get the same price as announced (excluding boxes and modems)

2) I was promised free installation (it was on the front page: "Free installation with sign up"). Disclaimer: the house was pre-wire. The guy put the cable box on the shelf and plugged the HDMI I left hanging in there and left.

3) My TV still doesn't work. I chatted with Cox and the representative says that he will send somebody over, saying that if he's a Cox issue, the tech visit would be free. The technician walks in, says that I need a tuner adapter and leaves. It took 5 minutes and I got charged other $45 for that. Shouldn't the first installation guy (who came a week earlier) install the tuner adapter for me? So I drove to Cox and got one from them.

4) Trying to activate the Tuner Adapter: First call, representative sends activation signal and tell me to wait 15 minutes. I waited for 1 hour and called again. Second call, Cox hangs up on me within 10 minutes. Then, I try the chat. This one is too funny to explain, so this is a screenshot of my conversation. 

So, I already have a $200 bill with Cox and I still can't watch TV. I've already called technical support and customer service several times. I've spent at least 5 hours already taking care of this.

Can anybody help me?
