Recording Conflicts - I can't record more that two shows at the same time. I should be able to record six.

I have an ARRIS Xi6A box.  Your web site claims that I can record up to six programs at once.  I am running into constant recording conflicts.  It appears that I can only record two at I time.  The other recordings show as "Recording Conflict".  I went to you Xfinity store in Dover Delaware.  They were no help at all.  They suggested I call Xfinity technical support.  I have tried calling several different Xfinity phone numbers and I can't get past the automated attendant.  Also, your Xfinity Assistant which is AI driven and I can't get anywhere with that.  How do I get help from a real technical person?  Or, is my problem that I don't have the right service?  I have tried the Xfinity app.  That's no help either.  I logged onto my Xfinity web account.  When I try to access my account details to see exactly what I'm paying for, I get a message that you can't access that information right now along with a phone number to call.  All the attendant did was tell me to go on the web site.  This is at least the third time I have tried to get information on my account via the Xfinity web site and it's not available.  Very frustrating.
