It's just another way to make money off you mate. Stuff like this gets under my skin. FWIW, Verizon Fios, if available has the modem/router unit which makes things a lot easier.
Finally, You have to understand these companies WANT you, Only if your uncontracted...Once your contracted their tune certainly changes with service. With Verizon I got into it with the rep just last month about my remotes. One went bad after probably 6 years and they wanted me to pay 14.99 for a remote..However I was out of contract then...So I told them to pick up their stuff. He ultimately convinced me into a new, Much cheaper contract for 2 years...But I also told him that deal is not happening unless I get 4 new remotes for the set top boxes I do have in my house...No problem Sir. Their argument was the remotes are disposable unlike boxes that can be repaired.
XM radio is another one...Those guys OMG with their pricing...Calm down Larzuk, Lol.
I don't want to keep this thread derailed, But I'll leave you with the advice of play hardball with any company you deal with...Threaten to cancel, and most often than not I've been able to get somewhere with them.
