Customer Service Issue

I converted to a business account a back in November because I was convinced by a salesman for DirecTV this would be a better deal. He assured me I would have the same exact service other than record from a separate DVR. He did mention I could not record and watch programs from the non-primary DVR, but would be able to use the Whole Home DVR service to setup recordings from the non-primary unit. He also never mentioned I would have to pay $299.00 for a Genie which I had previously.
A technician came out, replaced my 2 DVRs and took my old ones. He assured me I would have the same exact service other than record from a separate DVR. He did mention I would be able to use the Whole Home DVR service to setup recordings from the non-primary unit.
So here I am, having to pay for a Genie which I already had, and now without the capability to record or setup recordings from any DVR but the primary?
I spent hours on numerous chat sessions and on support calls with numerous folks in order to get Whole Home DVR service working to no avail. There is no record of any of your chat sessions emailed to you, and no case was ever assigned. I even spoke to a manager one time over chat.
Finally I figured out by talking to a senior technician, Whole Home DVR service is not supported on business accounts.
To say the least I am very frustrated. Frustrated by the fact I changed my service in order to save money, only to end up with a lot less features and an additional 300 dollar bill. Frustrated by the fact, there is no record of any of your chat sessions emailed to you and no means of tracking with a case number. My guess is you guys do use Remedy for case management or something to that affect?

​I've been trying to get a refund for the DVR I had to purchase and am getting no where. I'd also like to cancel my service and even though I signed a contract, this wasn't what I was promised. Who can help?
