Stealing money agent not responding and support to

I submitted a withdrawal request and I did not receive the withdrawal for more than a month, in addition to the agent for my account does not respond, and the support service available 24 hours does not respond either. I waited for more than a month and I did not receive the withdrawal. I did not receive the withdrawal, they say that the bank rejected the transfer, and the bank recovered the transfer. I told them that if the bank recovers the transfer, they will return the amount to you in less than a week, and therefore you must add the amount to my private trading account. Then the agent for my account told me half a month ago that the bank recovered the transfer and the XTB company will refund the amount to my private trading account in less than 10 days. Now it has been almost thirty days and they have not added my amount. In addition, the agent for my account does not respond and their support service is available 24 hours and they also do not respond
