From your explanations I do not know how your funds was taken(you can try and explain better), were you trying to send to an address and sent to the wrong address. Maybe your private keys aren't as secured as you claim it is, did you write or store it somewhere that's accessible to someone other than yourself.
I am desperate because these funds were supposed to be for my mother's health.
I just hope it's not just you sending to another address of yours, sorry I just get a bit sceptical when a line like this is added in this kind of post. If your mum is truly ill, you will have to find a different means of footing the bills.
The funds disappeared from my wallet without any action on my part. It was enough for me to transfer funds from the account to the stock exchange faster and there would be no problem. Please forgive me the nature of the post .... nobody will understand this situation because it is not about bills, but about a chance for health. These funds were 3/4 of the funds necessary to pay for a life-saving operation. Thank you for the answers ... now everything is clear to me.
