Where can I find Hebron Trust Bank in London?

You are dealing with one of the oldest scams around. Please do not send any money, or give out any personal information.

There is NO such bank in London. That's a fake name used in online scams
Check the FSA website https://fsa.gov.uk/register/firmSear...
That is the government site for every single registered financial institution in the UK. As you can see there is NO company named Hebron

You need to call your local police if you sent money or passport details as there is NO such bank in London or anywhere else in the UK
