High Broadband Speed Dilema Am I getting something for Nothing?

[hershon]

Help, Help, Help. Please give me your advice on this. This is totally bizarre and I need to know what you guys would do, forget moral ethics here, please! On Saturday, I ordered for an additional $30 a month, premium broadband cable service as opposed to regular. What this means is that your maximum download speed would double from 3000 to 6000 & your upload speed would increase about 40%. Anyway, the cable company said they could do this on the phone & in a few minutes I would have the premium service without having to do anything else. An hour goes by, I try to go on to the internet and I can't get on. I phone the cable people who appologize and they said this can't be done over the phone via their computer system anyway, they would need to have someone to come over and either install a new line and/or a new modem (they weren't very clear on this) on Thursday, but in the meantime they'd hook me back up to my regular broadband service which they did and I'd just be charged my regular rate. About 2 hours ago, on 4 random independent speed tests on 4 totally different sites (where I regularly test my broadband speed), I tested my internet speed- I usually do this once a day and the measured speed had basically doubled! I called the cable company up and they said I'm still being charged regular rates which will end when I go under the new plan on Thursday after their technician installs a new line and/or modem. They have no record of doing any premium broadband service on my account.
I can cancel the installation on Thursday if I wish and continue paying regular prices. The thing is, we're not talking morality or ethics here but common sense, the actual speed when surfing to different sites does not seem noticeably faster than before even though the measured speed via 4 different sites/tests is. Should I just keep my mouth shut and cancel the supposed installation or do I need the new line/modem to actually see my surfing speed double? I'm basically afraid that maybe they did a change, they don't know it or realize I'm not being billed for it, I'm slightly better off and should keep my mouth shut, or do I actually need them to install something to increase my web speed? I'm not on drugs! What would your recommendation be?
