I am finally convinced, Bitinstant is a scam.
They claimed to have resolved my issue on April 27th, and sent my coins apparently to an address on blockchain (which wasn't mine) but which blockchain claims is some sort of forwarding shared address for privacy reasons. Long story short, I never received the coins or a refund. I don't expect to ever receive the coins from Bitinstant and regretfully I have reached the conclusion that Bitinstant is a scam company.
Blockchain.info has a feature called oa shared wallet privacy. Do not use this feature. If you lose this feature the same situation that happened to me will happen to you. If Bitinstant forgets or due to technical reasons cannot send you your coins at the time it's expected and you used the shared wallet feature you will not receive your coins. Instead it will go to a random address.
In my case the coins went to that random forwarding address and probably was sent to someone else or got lost in the block chain. The lesson here is and which should be spread is that this feature is broken when used in combination with Bitinstant. In fact, I would say this feature doesn't work period as there is very little detail on how it works and on how secure it actually is and in my case it is now proven that its technically possible that your transactions can be lost.
Here is a copy of the emails I sent to Blockchain.info ---
https://blockchain.info/address/1CghGBzMDPVqPGb63Vyf9uWAh3JGwco9Un
In this most recent blockchain.info it's saying the Bitcoins 3.69843968
BTC were sent to that address.

Which are supposed to be forwarded to my address at -->

were instead forwarded to 1CghGBzMDPVqPGb63Vyf9uWAh3JGwco9Un ??
Can you tell me whats going on here? Does the oa shared wallet feature
even work?------
I received no response after sending several emails to their Zendesk support. It's safe to say that oa shared wallet does not work as I received no response and merely a "closed". See it for yourselves
But they never sent me my coins, never responded to me, and solved nothing, and I'm sure I'm not the only one. It's safer to buy your coins from localbitcoins. Dealing with corporations at this point is more of a risk than dealing with individuals in the community.
