In addition to the excellent suggestions above, It’s a good idea to have documentation about features and prices of the FIOS and Comcast off the rack packages sitting in front of you. But before you make the call, consider what bargaining chips would work for you…what might want them to add on to a package, like faster speed, more storage, extra channels or whatever, in addition to a better price.
Start the conversation off by focusing on a cable package that’s cheaper or better, or preferably both. Be sure to emphasize that you have been a long time Verizon customer that pays your bills on time and doesn’t call frequently to complain. Be prepared with numbers and extra features…I’m paying you guys $abcd.yz per year and Xfinity will be $efgh.yz with this extra stuff thrown in. If Verizon is offering a sign up deal, be sure to bring it up too.
And don’t let the rep think you are being wishy-washy about switching, they are trained to look for signals that you are serious about making a move right away. If you don’t like any of the offers, let him know that your next call will be to the cable company to sign up, weather it is true or not. You want to be the cool, calm, factual, concise Mac guy in the old commercials, not the blabby PC guy that will never switch to something better.
