Hey dilnbart,
That's totally understandable. If we're being honest here, I'm that person who calls 2 or 3 times after my first call to make sure the notes on my account say the right thing. Money is money and now a days you can't be too careful. I see the modem was manually returned and I can confirm there are no pending charges on your account for unreturned equipment. If anything changes, please let me know and I will take care of it.
Thanks,
Amanda
