Mobile Visa Card NEVER get received

In Sep 2022, I transferred to Xfinity Mobile with two lines and was told by the agent that I would receive two $200 Visa Cards for making the switch to Xfinity. However, even till now I haven't received them.

What is more ridiculous, I've called Xfinity and chatted with many agents multiple times in different sessions and they all gave me the same reply. The reply was that "everything is very good and you should receive the incentive in 5 to 7 business days." BUT WHERE ARE THE PREPAID VISA CARDS AT?

I'm very sad and angry about what the service Xfinity provides especially regarding customer services. They are brushing off customers all the time and don't give the exact answer people want. Their agents always rushed the calls/chats and don't help at all. I can give a specific example. Last time I talked with one agent whose name is [Edit: Personal Information]. I brought this problem to [Edit: Personal Information] and he looked very helpful. He said everything is good, don't worry, I've escalated this, you'll expect this incentive in a week, TRUST ME. I've asked the agent many times and brought up my concerns but [Edit: Personal Information] told me to TRUST him that I would get my incentive in a short time. BUT WHERE ARE THE PREPAID VISA CARDS AT?

I've been pretty annoyed by this and considered posting my experience to more audience in social media. I want to share with the public about how they perform and what their behaviors are. I've been a Xfinity customer but they are not able to help customers at all.
