Unable to withdraw

Apparently, a person from this company called me and told me that they are changing the company from UK to Austria and they have to liquidate all the account. We have to pay 10% fee to unfreeze our account. They sent us the following letter that I attach here. I only have 615€ but my friend has 64000€ and she has to pay more than 5000€ in advance to withdraw her money. According to the letter they are called ANTRAX GROUP, but instead of London, they are based in Saint Vicent and Granadinas. SCAM
