I had to call Verizon Wireless the other day about my bill because it seemed to be higher than normal. After talking with the rep I found out that they bill one month in advance for their wireless data card. OK
Today in the mail comes an envelope from VZW which thanks me for being a customer and encourages me to call their telephone support. What they also included was a nice handy reference card so I could find out my balance by simply dialing a few characters.
I'd love to see the customer service model and the savings this letter saves them on support calls.
