I received that same message asking me to call 615.528.4440.  When I called HSBC they told me they were aware of the scam.

When I called T-Mobile, they told me there was nothing they could do and that they have no way of helping me.  I am very disappointed that T-Mobile is doing nothing about this.  If my identity ends up being stolen then I will certainly hold T-Mobile responsible for refusing to take any action.
