t's a scam, totally unscrupulous, calls every day and asks you to deposit more money, it's not a bank, nor a trading company - from which the money disappears without a trace. They call from a PC and "spoof" the phone number so that it looks like your country code, are "stealing" the number and calling innocent people like them they try to recoup for their own gain. When they then "use" your number, you will be called back and asked what you wanted to talk about. And be very clear to yourselves that there is only one who can win, and it is they who steal your money. Do yourself a disservice and stay away from these scammers.
