Sprint Mobile worst service in my life Internet

Rather than resolve complaints, Sprint left me feeling like a ping pong ball.
I switched to Sprint because their unlimited data plan offer
beats competitors charging extra for every gig above two.
But despite their pre-contract claims that I would have both 3G and 4G service at my home location,   95 percent of the time I have either no data service or it is so slow pages take 2-5 minutes to load or just timeout. Video either doesn't play or constantly, endlessly buffers.
I have called and complained dozens of times weekly for five months to no avail. I get a different answer regarding the source of the problem for each call. And the problem had to be repeated for each call and to each rep, manager or escalation supervisor or tech rep.
Although Sprint occasionally acknowledges a temporary network service problem, they insist it will be resolved within a couple days. No explanation ever has been offered for why my data service doesn't work if Im at home. For awhile they insisted my home must be constructed of a material that blocks their signal.
But it is no better when I stand in the yard with no physical obstruction. I even downloaded their speed tester as suggested by the tech department. When I could get a sufficient signal to run the tests, up/download speeds often were below 100kps, not the 2-4 mps reasonable to expect from a 3 or 4G smart phone service provider. When I shared the test results with Sprint reps the typical response was that they weren't qualified to say if those were functional yet alone satisfactory speeds .
Since nobody would admit to a network problem, I was told I would have to have my Samsung Galaxy II S tested at the local store.
After they had tested my phone six times over a 3-month timerange and it passed all tests all six times, local store reps began advising me to cancel my service since I was paying $103/month for 450 minutes talk plus unlimited data.
Sprint corporate wanted the names of the local store reps.  I didn't trust then not to fire their more honest employees. They also repeatedly refuse to cancel my contract without paying an early termination fee.
Despite my phone testing perfectly six times (a big waste of my time plus having to reload all my apps and lose vital information each time....they didn't tell me the first time that my family photos including my last visit with my mother before she died in February would be deleted) Sprint insists there is "no problem" and I should just keep paying my bill. They finally did give a small discount on my bill this month but insist I must contest my bill each month regardless how poor the data service is at my home where I am 80 percent of the time.
When in town at the Sprint store the phone works great.
In the future, I would gladly eat s**t rather than try to get Sprint to make sense or provide me with the service I am paying for.
