Internet 5G residencial

After ditching Brightspeed and their 15mbps speeds, we were thrilled to get T-Mobile 5G home internet. Worked like a champ for about 6 months. It has been almost worthless for the last 4 weeks or so. This is our 7th month. I have called countless times to always speak to a pleasant tech support specialist. They are so nice and quite capable of helping you restart your gateway. That's about it. Whenever I ask about my logged internet drops and slow speeds, I get nada. They acknowledge they can look at it but never address what they see. It is always "a tower issue in my area". It has been almost unusable for the last few days. We are disappointed. It has gotten so bad that I will go with Starlink for three times the money plus equipment costs. We have no other options. We are located about a mile from our town, with fiber everywhere except by our house. Spectrum offered us a deal at $7500 to bury cable to our property! So, I will return the T-Mobile gear as soon as I get my link up and running. I understand cell phones get priority on the towers, but one can't help but think it is a throttling issue.
