Earlier quoted context omitted.
Charge CEO here. We can definitely disable voicemail for you. I actually have it disabled myself. Just send us an email to get it removed. We should probably just add a checkbox for it in the management UI though now that I think about it.
And this is how you run a company, everyone please take note. User feedback is actually seriously considered and responded to in an acceptable manner.
Now, each individual case where an employee unexpectedly helps out is great, but this is NOT 'how you run a company'. You should focus on getting your general customer service and support lines to be good.
I've never dealt with this company before, or even heard of them until today, so their normal lines of support might be great. This isn't meant to be a specific criticism of Charge.
However, it does seem odd to me that a phone company appears to give no contact phone numbers on their web site. That's not a good sign!
