Credit Suisse Bank review: Inheritance Scam

I received a email from a attorney in the UK by the name of George Wallace, stating that one of my family members had died in as car accident, and he had a certificate of deposit that needed to be claimed by a family member. He gave me his information I called him and he explained the situation. He needed information from me to verify who I was, so I sent him a copy of my drivers license. He then verified who I was and connected me through e-mail to Mr. David Mathers who works at Credit Suisse Bank, who began helping me with the transfer process. Mr. Mathers stated since I was not a UK resident that I had to pay a attorney to retrieve Mr.Freeman death certificate, letter of administration and a affidavit which cost me 850 British pounds, but $1417 US dollar. Which I paid through MoneyGram. Then I had to pay for bank administrative charges which was 1250 British pounds 2119.60 US dollars. Which I did once again through MoneyGram. After that he the sent me a email stating that the inheritance had be put in a flexible non-resident account and that I had to pay the FCA 5, 000 pounds for a access code, to have my money transferred from the non resident account to my US account. This is what when I called the FCA London and spoke to someone and they told me they do not handle access codes and this is a scam. Can someone please help me. I am out of 3, 552.55 dollars. This has caused such a hardship on my family. Someone please help.
