Account # [Edited: "Personal Information"]
On Nov 20th, 2023, with high hopes i switched from T-Mobile to Xfinity mobile using Xfinity reward program (830$ off - Code: [Edited: "Personal Information"])
I connected with support personnal and he confirmed my eligibility and switched to Xfinity. I got a new device - Google pixel 8 pro as part of this program.

But promotional reward was not applied and i have been trying to reach Customer care via chat, phone calls. But none of them were able to resolve this case. Tier 3 or background team found that, it was tagged as New connection and they need to change to Port In to apply the promotional offer. But still this issue is not resolved and i spent hours and hours of time to talk to support team. All of them giving me false promoises and nothing resolved yet. You can refer all the chat history against my account. Total 3 cases numbers created so far.
