False Advertising and Very Poor Customer Service

Several weeks ago, I purchased two I phones from my local XFINITY store.  I purchased them on the condition that I would receive two $150 visa gift cards in conjunction with my diamond status.

I finally received my reward but to my dismay I received only one $150 gift card.  I went to the XFINITY store and the both the clerk I purchased the phones from and the assistant manager told me that they would submit some sort of ticket and get it resolved.

A couple of days later I receive this email response, "Just following up on the ticket we created the other day.  I received the response that You have received everything from Xfinity rewards that you should.  The Diamond Reward $150 visa card was per account not per phone. There isn’t anything missing".

I follow up with this response to the store, "Thank you for looking into that for me I do appreciate it.  However, I believe the information you received from the rewards department was incorrect.  Please see the attached screenshots.  Both were obtained from the claimed rewards section of my account page.  Notice that the product benefits lists "each" mobile phone purchase not 'per account'.  Furthermore, the terms and conditions list " 10 eligible phone purchases per customer/account".  This would not make sense if it were limited to one per account as you have indicated.  I know you are busy but please re-confer with whomever responded to you and share the screenshots with them if necessary".

This is what I received as a response from the store, "I reconfirmed.  Best"

I follow up with this to which I receive no response, "Does this mean that customer support confirmed that I am not entitled to another reward despite what the screen shots say? Or does it mean that you resubmitted the inquiry to them and they are looking into it. Thank you for your time".

After waiting a couple of days I responded with this, "Please answer this email. If you have not/will not pursue this any further then just tell me so that I may proceed to pursue it another way. Thank you".

I received this, "

I have been out, I had surgery Tuesday.  I still have received only confident statements that you have received all the credits & prepaid visa cards you are entitled to. Be Well".

Now I am really frustrated.  Is it really that hard for the store assistant manager to tell me whether or not my ticket is still being looked into?  If COMCAST/XFINITY is going to advertise something they need to come through and deliver it.  Furthermore, it's not like I haven't been paying for premium tier service for the better part of 20 years.  Is this how XFINITY treats their customer base with proven longevity?

Attached are the screen shots I referred to in the post.  Names were left out of the email excerpts.

Trying this forum method because hopefully an agent will see this and respond/take some action.  Tried 1-800-XFINITY and the agent was not able to help me and gave me the number to the rewards department which I cannot call without taking off work because their operating hours conflict with my job.
