Waiting since 5/24 for response re: changing Xfinity Rewards tier

I've been an Xfinity customer since before 2011. However, my rewards tier is only set to the Gold level.

- On 5/24/23, I filled out the form on the Xfinity website to request I be changed to the correct tier. I provided all the requested information. The confirmation page said I'd receive a reply in 7 days. I still haven't heard back.

- On 6/11/23, I reached out to customer service via chat and was promised a response by 6/18 but still didn't get it.

- On 6/20/23, I spent over an hour being bounced back and forth between reps on the customer service chat and was, once again, promised that my request was escalated with the rewards team and it would be expedited. Over a week as passed and, once again, nothing.

It's been well over a month and my rewards tier is the same. I would like a solution and to not get more empty promises. I hope that I can find a resolution here. Thanks in advance for your time in reading this.

UPDATE 7/11/23: The issue is still unresolved. In case any other customers are following this, the response I received yesterday was: "The Rewards team is needing to work with our Engineers/Development team to resolve the problem and let us know a few days ago it may be up to 3 weeks before we have a resolution, but they hope much sooner. They will get it fixed, but it is going to take some time." 

UPDATE 9/2/23: This still remains unresolved. Now they're telling me they have no estimated timeline regarding fixing my rewards tier. I'm beside myself. After dealing with this issue since the end of MAY 2023, the idea of switching to another internet provider is looking really good to me right now. 

UPDATE 9/13/23: It's official. Xfinity has lost me as a customer. This situation is so unfortunate. Even though they confirmed that my rewards status change was approved back on 7/26/23, they cite a technical issue that has been stopping them getting their system to reflect the change. And they will not work with me to provide any rewards or other solutions as a courtesy (such as Peacock) in the interim (as they still don't have an ETA for the technical "issue"). Xfinity clearly doesn't care about retaining their customers. I'm moving on.

UPDATE 10/19/23: Unfortunately I wasn’t able to find reliable internet from a different provider so I remain a customer of Xfinity. Much to my continued frustration, there still isn’t a resolution with my rewards tier. So disappointing and unbelievable that such a large company can’t get their act together and provide a service that they advertise to their customers.
