Sales Rep - Official Complaint

I have been trying to resolve a rebate issue since March, and I am extremely disappointed with the lack of communication and follow-through I've received.

Initially, Adrian [Edited: "Personal Information"] advised me to contact the CBM Missing Promotions Department (800-211-4131). After speaking with them, I was informed that Adrian had provided incorrect information and that he needed to submit an escalation on my behalf. I followed up with Adrian multiple times over several weeks and received no response.

Eventually, his manager, Sean [Edited: "Personal Information"], took over my case. Sean advised that he had submitted escalation ticket [Edited: "Personal Information"](end of May), but he also stopped responding to my emails after his initial one. Despite several requests for a status update, I have received no communication.

We chose Comcast Business largely because Adrian repeatedly discussed a $1,200 rebate during our sales conversations. To date, we have only received $800, and after months of trying to get this resolved, I still have no answers.

At this point, I would like to file a formal complaint regarding the handling of this matter and the complete lack of responsiveness from both Adrian [Edited: "Personal Information"] and Sean [Edited: "Personal Information"]. I would also appreciate an immediate update on the status of escalation [Edited: "Personal Information"] and a resolution to the remaining rebate amount.

For reference, I have included both Adrian and Sean on this email thread.

Thank you for your prompt attention to this matter. I look forward to your response.
