Today I needed to update some payment information for my Cable service. After taking care of that with a billing rep I asked her to transfer me to the sales department.
When I got the sales rep I simply asked her if I might qualify for any promotional discounts right now... and she immediately said YES! Just like that I was able to knock about $30 a month off my bill for 12 months or about $360.
Not bad for a three minute phone call!!!
Give it a shot! The worst that can happen is they will say no!
