20 Year T-Mobile Customer - Customer Service had become very inadequate, terrible. Rude.

I've been with T-mobile for like 14 years, honestly it wasn't bad before Covid, but after Covid is when I started having issues. My first complaint is that there's no upgrades on phones for existing customers like me, unless you add a line. I still have the iPhone 10x that I actually had to replace because I drop it 2 feet from the floor while vacuuming my house, and the screen got a bad line in it that was neon purple, I use my phone for work so I ordered a replacement phone using the insurance. New phone came came pretty fast, but after a week the battery would die I couldn't go anywhere without a charger, so I called and customer service was nice they sent me a new phone, but told me if it shows that there's nothing wrong with the phone battery I might be responsible for paying full price for the 2nd replacement phone. The 2nd replacement phone worked much better. 
 

My other complaint is that my kids dad got them iPhones 14 for Christmas without taking to me, but changing my son's phone over to his dad's account was a nightmare. They wouldn't let my son keep his number, and I got charged for 3 months after canceling his phone line, and had to call into t-mobile 3 times every time I was told it was fixed, it never was, finally got it fixed but was never offered any kinda credit for being overcharged multiple times. 
 

my final complaint is that I use my phone for work I'm self employed, I've tried multiple different times to get my phone plan switched to a business line, the first time I asked about this, I was transferred to the business department, only to be told there was no one there after being on hold for 30 minutes and to call back later, I was Surprised because it was around 3:30 pm central time. The second time I called in to change to a business plan I was told I need to go into the store. I'm honestly thinking about leaving T-mobile the last two years have been a pain and my phone bill is outrageous I have one line and I'm paying $100 a month for a crappy iPhone 10x because the upgrade really aren't upgrades unless you are a new customer to T-mobile. I don't feel appreciated as a long term customer.
