IS there anyone at AT&T that believes in CUSTOMER Service - SCAM Bait and Switch

I order uverse and the AT&T internet back in January of this year. The night prior to the install I receive a cancelation notice because AT&T side they could not offer the 24 mps that I ordered but offered me a 18mps and promised it would be constant. The explanation is the "pipe" to my house is only form me and dedicated at 18 mps. The second appointment was rescheduled when the technician was in my driveway. The reason is customer service entered my neighbors address and even though I met him, he could not complete the work. Third time is a charm; they completed the installation but forgot all my equipment and it took three weeks to get it corrected. My timeline - 2 weeks to get the install from the original order. Now the bigger problem - Called in after one week because there was latency in the network and I could not run Netflix and two workstations at the same time. AT&T tech logged in and stated corrected the problem by reconfiguring the modem. A few days later I called in with latency in the system and a tech dialed in again and "fixed" this issue. The third to customer service was to cancel my contract. Note this is on day 28. The call got escalated to the "highest" technical department that promised me the very best resource will be sent to my house to resolve the issue. Interesting that it was scheduled after my 30 trail but I agreed based on the cost of the bundle. The tech arrived and replaced my modem and "reconfigured" my setting. The next day my system freezes and I am ready to lose it. The next call was to technical department who sent another "Outside" technical resource to confirm my network coming in is correct. Once again I am promised the changes would correct my problem. Once again my system showed freezing up. If you are still with me you think I am very patient. I have 5 kids at the house and have to explain on a daily bases AT&T is working on a fix. The fourth technician within 30 days was recently at my house changing out the modem again (third time). The ports where changed outside and the system was "reconfigured" again. The next day my system is freezing. In the first 30 days of service I have over 30 hours logged on the phone with AT&T and multiple technicians at my house which in hours of me having to be home. I have removed the system from my house on 3/20/17 and called AT&T to explain my concerns and the yet on the phone again for 1.5 hours and I am will the wrong department. I cancelled and yet AT&T want to change me a fee for breaking a contract AT&T could not fulfill. NOTE: Each time I called with a problem AT&T said the best way to fix it was to switch to Direct TV. The last two technicians that were at my house stated AT&T cannot provide the level of connectivity that is required to run my TV’s and internet. QUESTION TO AT&T - Is it common practice for you to sell something you cannot deliver and then charge a cancellation fee because I cancelled the service? This is a bait and switch to sell the Direct TV service. I am looking to the BBB to see how many hard working people are charged for products and services AT&T cannot provide.
