how to leave a good customer service review?

I miss Sprint. T-Mobile is a terrible company to have service with. I've been a loyal customer for years even after Sprint was bought out, but after my recent experience, I'm seriously reconsidering my options. I had an issue that needed resolving, and the response I received was incredibly disappointing. Not only did they fail to help me with my problem, but it became painfully clear that they don't actually care about their customers. Instead of providing support, they seemed more interested in collecting money. It's frustrating to see a company I've trusted for so long prioritize profits over customer service. I expected better from T-Mobile, and it's clear their focus is no longer on keeping their customers happy. I won't be recommending them to anyone in the future.
