OP Results:: I've been with Verizon forever, it seems. But several times lately over the past couple years, I got over-billed, A LOT. And, I was able to go into the local Verizon store and resolve it.
Now, with recent changes in policy, many of the "fixes" are no longer available at a store, and we must call a specific number - which I did, on hold, and several times. Each time, it was "resolved" on the phone, but then same issue on the billing next cycle. After numerous wasted hours, I decided to change.
I refused to pay the bill unless adjusted. Once the bill was past due, and late fees added, Verizon called ME and threatened to shut me off ... GO ahead I told them, I'm changing companies anyway, and hung up. At that point, within ONE HOUR, I received a new and accurate billing via email ...
I paid it, and will think about changing still, but have been with this company so long, it's best not to wiggle the phone lines at this time. And, of course, I'd have had to buy a new phone for more money than the bill itself. But, if it happens again, that's the end of Verizon for this family.
My time (and yours, all of ours) is as valuable as any Verizon employee, and when it's spent on-hold, and repeating the same story up the lines of management numerous times, then it becomes more than just annoying ...
Verizon might be the best coverage, but is also the most expensive. At some point, we have to weigh the worth against the hassles.
