If they are not, then whom did you talk to?
And what make you think by talking to the supervisor/manager, you can get the deal out of it?
Yes, I totally feel your pain as I hit many times, up to the point that I realize talking to a CSR or his/her upper-level personel are freaking the same, they are all crap anyway. And up to the point that I just throw my stuff away, avoiding calling CSR and got severe headache afterall.
I'm not talk about Tomtom alone, name anything comcast, verizon, att, .....
