" Longsdale Capital " was the name of brokers Metatrader account source...
where have you been for 3 years? what have you been waiting for so far?
how do you expect any help here, if we don't know the name or anything about the other side?
Fake investment platforms or even exchanges are very common ways of scamming. They lie to you about your potential profit, why do you think they left the actual info anywhere? All names which you mention here, IQOption, Longsdale Capital or whatever are just your suspicions and you haven't any proof of that (to be clear, I believe in your words). Unfortunately, we can't provide much help to you, especially not after 3 years. I believe scammers also already forgot about your case.
