Why is there mysteriously no longer signal in my house after T-Moblile/Sprint Merger?

My husband and I have been Sprint customers for years.  We had fairly decent cellular service in our home, maybe losing service twice in 4 years due to major storms messing with the towers.  However, for some unknown reason that makes no sense to me (I'd assume service would improve), we now often entirely lose cell service completely at our home and within a 1 mile radius ever since we were instructed to change our SIM cards upon the T-Mobile/Sprint merger.  Not only is this frustrating, but my business and sanity are suffering.  I did not choose to work with T-Mobile.  We had a contract with Sprint.  Sometimes service is fine, but then for sometimes several weeks at a time, service is completely gone.  We have tried recalibrating our phones, etc.  My husband uses a Samsung Note and I have an iPhone 12 as well as a business cell that is also iPhone.  All 3 phones stop working for calls and texts for weeks at a time.  It is so unreliable and I am ready to find another option at this point unless this can be fixed.  We have tried working with technical support who work with us a bit but then try to tell us service is just sort of weak where we live - which may be true, but why did it work consistently for several years when we had Sprint?  Why all of a sudden do I rarely have signal in my home?  Is anyone else experiencing a similar problem?  

Same here. My wife still has her sprint card, I have to use her hotspot just to post here from home
