Yes, PLEASE!
The box isn't so valuable that they would offer so low. When did you sign up? Also, do you have TV also? You only mention phone and internet in your ()
What happened?
I had optimum for 65 and I was sick of their service, so I signed up for Verizon and they installed a fios box. Then when I called to cancel optimum they promised me the world. Optimum lowered the monthly charge for a year and gave me 50/5 Internet.
I then canceled Verizon.
I kept getting mail from Verizon with good rates for a triple play, and started singing up only to realize it would be 85 a month so I dropped it.
About 2 weeks later I got a letter from Verizon that they would offer me a credit of 10 a month, and there was another deal I found online for another 10 off and I put the deals together.
But not before I told Verizon I would cancel because I am getting 50 mps from optimum. They gave me that too.
