Hello,
None of what you mentioned really occured, it was probably a breach in your security system. And, yes, again as you mentioned, that certainly was an extremely frustrating experience. But what is more frustrating is that you hold no responsibility. I was totally sure that my funds would be safe with you, blockchain.com wallet was chosen, because I trusted you.
But this is the point where trust ends.
That was not my fault. My computer is always double-checked and secure, and I never visit phishing sites or extensions. Such response from you, no help or compensation offered from your side, makes it even more frustrating.
I will never use again and will discourage other people to use your service.
I am also going to make this situation and our conversation public.
