I had the same problem of a 411 call charged on my June/July 2020 Verizon bill. I had to look up what 411 was--I have never made a call to 411. The charge was $1.99 + taxes/fees for a total of $2.85. I called Verizon (on hold forever) and the person was helpful and she said they will credit my next bill for the $2.85. Will be looking more closely at my bill going forward but this shouldn't be happening.
