Here’s the deal: I already requested the cancellation of this service and they canceled it; then when I disabled and re-enabled the SIM card it came back even though it had been canceled. I called the ombudsman and requested cancellation; they canceled. Today my phone stayed drained the whole day and when I finally managed to turn it on I came across this:
I always go to Reclame Aqui; it usually works, but in a recent thread here they talked about a complaint channel on consumidor.gov.br, and many users said that their problems were resolved—perhaps it’s a good option?
The problem is that the service is being reactivated; I could already have registered on these channels, but nothing guarantees that the same thing could happen again.
