Fidelity Investments Reneging on Corporate Bond Trades and Illegal Borrowing of Shares Cincinnati Ohio

Once again Fidelity mysteriously reneges on it's bond trades that publicly are shown to take place but mysteriously get erased when the buyer finds shares cheaper soon after and this in turn hijacks your shares in pending mode without being able to be traded and without notification that the trade was canceled even after it sold at your ask price.
Fidelity has a new trade system on bonds that won't allow for ask prices to be more then 2 points away from the valued price or bid price which was supposed to be a solution to these canceled orders however that method is illegally controlling and manipulating bond prices or trades to their advantage when they put bids way lower then value price and way lower ten trading prices for the day thus creating an inability to sell at supply and demand legit pricing, allowing them to pick up shares cheaper or higher margins on the bond sale for Fidelity at the cost of it's clients.
The bond sale canceled was only 1 point (1%) above trade value which was normal for the type of high interest this bond paid and the market trading at this time so any cancellation should not have been allowed by Fidelity and any hijacking of a bond (called borrowing a bond) is highly suspect and illegal.
Fidelity has been told over and over again about this type of business practice at it's bond trading desk but they've yet to solve the problem without causing even more infractions.

After a few days no resolution to the reneged trading or holding of my bonds from being traded and even more money disappeared from my balance from the following night.

Things got worse as they threatened me not to write them if I have problems, and not to call the mediator who told me to call anytime I had issues with the fixed income desk. Even though Fidelity themselves gave me his number I was threatened for calling that number they told me to call...
WHAT??????? Am I being set up?
Lots of displaced blame took place but still no resolve to this issue.

I asked them about their guarantee on their web site and commercials-
"guaranteed trades"- BULL!
