I did made transaction to coinbase.com my wallet on XXXX XXXX of XXXX at XXXXXXXX XXXX my XXXX time zone. The transaction was made with the quickest option which is instant reflection on my wallet. But that thing did not happen and until today I am trying to resolve this issue XXXX tried on live support so many times no resolution. Than they said will respond via support chat so many times, than email but after so many emails no resolution, my money are still not refunded to me until this days. I send them so many emails they responded that my bank requested the money to be send to them, which was not the case after I spoke to my bank they said that they never made such request ever and that I should talk to coinbase again and again. 
I did try to do that I send them so many emails there is no respond what so ever regarding my problem. I presume that something happened with my funds and they dont like to explain what happened and they making some responses that I check with my bank and those events never happened. Until this day there is no responding on my email requesting my money to be refunded to me as soon as possible. They just send me an email few days ago avoiding the problem that they restricted the usage of my coinbase wallet and that was it .Since than I have wrote again and again so many emails please check the content of my emails below just the last XXXX they were XXXX. 

Hello There to what ever person I am communicating with, Keep ignoring my emails for what ever reason making feel that I have done something wrong .Let me tell you If you are based in the USA I will escalate this case to the FBI and CIA or some of the USA governments institutions which I will find out which one is the most appropriate. 

You keeping my {$1800.00} since XXXX XXXX of XXXX do you understand that, for unknown reasons. 
I can not care less if you limit the Coinbase account that is not my issue, my issue is the money I transferred to your exchange. 
Please refer to my previous emails and refund the money in question as soon as possible. 

This can not continue any longer this is not wild west this is civilised world of dealing with clients.

After further review, we received a formal request from your financial institution to return any available funds back to your bank account. However, the funds credited from your bank transfers have already been utilized and moved off our platform. For additional information on this request, please contact your bank. 

I did refer to this issue which you addressed here in red, but nothing what you saying here is the truth. My bank which I spoke to in few occasions never initiated anything like that because they confirmed that with me. My bank also advised me to tell you that they never received any return of funds to the amount of {$1800.00} and they advised me to sort out the issue with you. 

Please do address this issue expeditiously and do not continue to ignore my plead my money to be returned to me as soon as possible .I spoke to XXXX they can not do anything because you are not XXXX registered company. 

Please the truth is on my side do not continue this, and please address this issue as soon as possible I gave you all my details and instructions what to do in my previous emails and you completely ignoring me all this time.
