I would keep trying if I were you...I was afraid that the information would be different from person to person within Verizon, a lot like the DOT!! As a matter of fact, we spoke with someone the other day that was interested and I suggested they NOT go into the store for that very reason. Try again and if the person doesn't want to grandfather you in, ask to talk to their supervisor and take it from there. I've heard of people seeing things more clearly when they're reminded of how long you've been with them, what you've spent in that time, and maybe you'll have to take your business elsewhere....hey, whatever works!!
I really think these two new plans they're offering are gonna come up and bite them. The people are WORN OUT with paying more and it makes no sense to offer a device that connects 4 more computers and then offer only plans that are limited....unless of course, it's a scam that they don't want to talk about!??
