In general, I became a victim of fraud and this is due to bitcoin wallet. I'll tell you from the very beginning.
I got a job in one office, which deals with money loans. My task was to communicate with debtors and for every payment I had to receive 5%. One debtor asked his supposed friend to make a transfer to my account. My supervisor approved this and said that I hsve to take this amount and put on a bitcoin wallet. Today I got a call from the bank and said that the person who sent the money requires them back, but I already sent them. My supervisor does not answer me, the bank was told that they will contact me when the main office processes all the information that I gave them about the company and in general. In the bitcoin shop, I was told that money can not be returned if you have only a QR code of your wallet and an address. I do not have that amount to return that person (4,500 euros)
How can I return this money back? To hack this account or something like that. If someone does this, or knows someone who does this, I will be grateful for any information.
It was an inside stuff at your company's premises so why in the first place we will know what actions should be done. There are some confusions on some part of the story but I will not take it for now as what matter here is and must be prioritized is....
..by taking it on legal and asked your supervisor. What kind of supervisor you have if they didn't answering your calls. Talk to your bosses and plan for a counter. You guys there have to collaborate with each other to solve that case. No way it can be solved by posting it here in the community.
Unfortunately i wrote my supervisor begging messages to return money but i have no answer
May be it is possible to hack this bitcoin account somehow?
No. Focus on contacting him first. What kind of office is that? You even don't meet your supervisor personally?
