Can't get Tmobile and Assurant to agree on my coverage

I'm hoping after a year this situation is resolved! My only hind sight advice, would be is to get manager on either side involved, and keep escalating the situation if not resolved to your satisfaction in 48-72 hours. FYI, if you do have Apple, you can pay monthly for Apple Care, instead of all at once. I don't know how that would work with an older phone though. Can't hurt to ask. 
 

But the main reason I replied to you after a year later is I know your pain with AT&T! You could have been describing our situation. We had been with them for over 20 years, most of that time with husband being an employee! Just the past few years my husband hasn't been affiliated with AT&T, and they didn't even realize it! So this is how they treat their employees as well as customers. The last straw was that they wanted us to pay for 5 G, when it wasn't available where we live. Plus charging us for 5 G, that would entail charging for all sorts of features we didn't want. My phone was paid off, husband was close, so we paid his off and went to TMobile. It's only been a month, so hopefully it will go well. We went with the AppleCare, since we had a few months left on the old phone. They transferred it to the new.
