why am I paying for this

I recently "upgraded" from my OnePlus (veteran) plan to the Go5GPlus plan and my service is still terrible. I additionally lost previous capabilities I had with my original plan. Not only has my bill gone up but service has not improved. How to I revert my plan back? The 5G network is no faster than the throttled 4G I had previously. 

While on the phone with customer service to upgrade my plan I also wanted to upgrade my phone. The phone was processed 12 July 2023. I have not received the phone or any delivery updates. 

It was not made clear the amount the phone bill would increase or the capabilities that would be lost (e.i. $4.99 FAMILY Netflix). 

Lastly, I am being prompted to return my trade-in. I have not received the phone, yet the 30 day timer is counting down. 

I am disappointed and would like to be contacted immediately on options for terminating the plan or remediating the situation.
