IG stole my money

IG has stolen money my account is DW6VV i had deposit 2500$ and i earned 2359$ profit at first they did not return my money, so i sent around 15 withdrawal requests and after those 15 requests- they cancelled my profit!!! now they send to me some messages about breaking the agreement, but when i ask to say what exactly i broke and if they have any evidence/proofs of it- they do not answer. and it lasts for 3 weeks already. they just do not care about my situation or send some typical emails.
