Mint Mobile review: Poor sevice, even worse customer service

In early June, I began experiencing trouble connecting to Mint's cell service at my home, despite being less than a mile from 3 towers. I also found that I could no longer use wifi calling. All attempts to correct both problems using the Mint app on the phone and the Mint app on the computer were unsuccessful.
Calling support required several hours on the phone explaining the problem to people that could only follow the script without fixing anything. several times I was told to wait for up to 72 hours for the problem to correct itself.
My subscription auto renewed during this time period and I was never able to get service.
