is a company called fine power device, working with T-Mobile doing promotions and surveys

I got an email from T-Mobile and it was saying that I won an iPhone 14 and all I needed to do was a small survey with T-Mobile, which I did and they told me I won an iPhone and all I have to do is pay for shipping, when I did that , the bank blocked the payment, so my question is to T-Mobile. Do you know a company called fine power device, that is doing promotions and surveys on your behalf?
