Is it possible that Verizon could have screwed things up more than this?

Question

I contacted Verizon 10 days ago about internet and cell phone service the person I spoke with told me that Verizon did not offer internet in Illinois and I should call something called Frontier Communications
I should have taken this as a sign that I shouldn't do business with Verizon
Instead I went to your office on State street in Chicago. I was told that
Verizon does in fact have internet, they have an arrangement with ComCast. I was told
if I signed a 2 year contract, the first 6 months would be  $20 a month and then the price
would be $40 a month for rest of the contract.
I signed up and was given an account number and a number to call ComCast
When  I spoke to Comcast, I was told that there was no agreement with Verizon
I went back to Verizon, Verizon called Comcast. Now Comcast was saying there was a agreement but the terms were different
It was now $20 a month for 6 months, but no contract. After 6 months there was no guarantee what could happen
to the price. There could be another promotion,  it could go up
I agreed reluctantly and signed up
The earliest appointment was the following Monday.
I had to leave work early for the appointment. I won't get paid for this missed time
I was given a time frame for when the ComCast Technician would show up. He was late; he arrived after the timeframe
I had ordered wireless internet. I know I ordered wireless because I discussed this with the comcast rep when I placed the order
We talked about how many devices could use the wireless at the same time, how far I could be from the router, whether there was a separate router and modem or if it was one unit, if I could buy my own rather than rent it, etc.
The technician did not have wireless equipment with him. He said the order didn't indicate that it was wireless.
I asked if he could install what he had since I had been waiting almost a week for the internet and then I could go to their office to swap it
He said no, a technician had to install it. If he installed what he had and they sent out another technician later with a wirelss router
they would charge me a second installation charge
The worst part though, is the earliest they can have someone back out is Wednesday ,ten more days later
That means almost three weeks with no internet at home and I have to take off from work again and lose more pay to wait for the technician again
I do computer support. I'm on call for work. If I get called out at night and don't have internet, I have to go downtown in the middle of the night

Answer 1

I understand that you are frustrated with the yes/no/yes regarding internet through Verizon.  I am assuming you are referring to DSL or fiber optic internet with Wi-Fi, since you state the internet service is actually provided by Comcast.  That is as far as my understanding goes.  Your post is titled "Is it possible that Verizon could have screwed things up more than this," but the rest of your complaints (please understand I do not argue the validity of your anger or frustration) are, in fact, regarding services rendered (or not) by Comcast.
I used to have a bundle with Centurylink internet, Directv satellite, and Verizon Wireless.  I got a separate bill from Verizon but I got a discount for the Centurylink and Directv bill by linking my cell phone numbers and creating a "triple play."  Centurylink had ridiculous scheduling issues with their techs, and it took five calls and two weeks to actually get the internet hooked up, at 1.5 mbps as the lines couldn't accommodate the 10 mbps the rep offered.  I was upset with Centurylink, not Verizon.  I had upgraded my cell phones through Centurylink, but if/when I had any issues, I called Verizon.
The issues you are describing are not within Verizon's control, which should have been clear when you had to speak with Comcast to set up the account and order.  You need to call Comcast to resolve it, and the sooner the better.  I had a horrible time trying to recoup money I paid to Directv after breaking the bundle, and eventually Centurylink refunded my money since the were the ones refusing to release my payments to Directv, saying I had a bundle but they could not discuss billing for Directv service. Almost all companies have a window for refunds and billing disputes, and Centturylink gave me the runaround until I demanded escalation.  Once the dispute period is over you don't have a leg to stand on for credits or anything else.  I had to get noisy to get results, and you might have to as well.
Step one is calling Comcast and placing the blame where it belongs, then work toward a solution to rectify the lost time and frustration.
