Help me

I have a few things that have problems with first thing is a representative sold me the prepaid Internet, then I have a TV box come to find out the TV box will not hook up to the prepaid Internet, so that doesn’t work anymore. Now I would like to trade in a phone and upgrade to a Samsung and every time I’m on the website it says technical difficulties then I call and give the runaround and transfer here transfer there and then put me on hold and then transfer me somewhere else and they said 19 minutes before they can get to me I’m a diamond member. I don’t deserve to be treated this way not saying that I’m better than anyone else. Just think that the processor should be so much easier. Give me so much anxiety
