Verizon is throttling me for abnormally high rates of bandwidth. Please explain?

I have called several times to Verizon in the past months because my iPhone has been getting such slow data speeds according to several speed test apps from the app store that I purchased. They all are very similar in their results so I know I'm getting very slow speeds both in the results and my experience in the web browser, safari. I was told 2 days ago by a tech rep that a "data 'optimization' feature" was put in effect on my iPhone and was the cause of my slow data speeds. She continued to do research on my account and told me that the throttling shouldn't even be on my account because I have never gone over 2gb of data usage. She said the highest I have ever used was 1.8gb and that was at the beginning of the year when I first got the phone. She gave me a number to a special department that handles the throttling feature to have it removed as I did not qualify or meet the criteria for "optimization." I called today and they said they couldn't because they don't have the authority. They then transferred me back to tech support and was back to square one. I just spoke to a tech agent named Joseph and he told me in detail why I was being throttled but I will summarize what I was told. He said I indeed have a "network optimization" in place on my account but it wasn't active. It's there because my iPhone is pulling far above normal or average speeds. He then told me I was connected to their EV-DO Rev. B network and made it sound like I shouldn't be. When he said Rev. B I was shocked. From EVERYTHING I have been told by workers of Verizon and research on the internet Rev. B is a dead project by QualComm. CDMA carriers were planning on upgrading to it but decided not to once LTE was announced and they decided to jump on that band wagon and pursue 4G rather than 3.5G, which Rev. B is considered. Rev. B has average 4mbp/s down and 1.3mbp/s up with max peak rates of 14.7mbp/s down and 1.7mbp/s up which we all know Verizon has and never will be capable of. So the question(s) is/are this: 1. Are they allowed to throttle me based on bandwidth not usage? 2. Does Verizon really have Rev. B or was the rep I talked to full of sh*t? Thanks in advanced. Best answer receives 10 points!

Every time someone from Verizon opens their mouth, nothing but s**t comes out.

This is why I've been with T-Mobile for ten years.

We have two smartphone on our plan, and we rarely hit the 2 GB throttle limit, and we never have issues with data speeds.

Just sayin'.
