When I got my Acer laptop three months ago (it's my first windows 10 computer), I set up a Microsoft Outlook account with a password but
only a pin to access my laptop. I have accidently entered the wrong pin too many times and the reset doesn't send a verification code to my mobile, I must have entered it wrong

The login screen doesn't give me an alternative way to log in; such as with my outlook password and if I use my daughters laptop to access my Microsoft account, I can't access the security settings because of the blocked pin and incorrect number to send the the verification.
Therefore what other option do I have to unlock my Winds account?I am 82 and housebound and my daughter has a full time job, so my laptop is my lifeline to the outside world which I have now been unable to access for a month and my daughter has had to make a special trip so that I can write this. Microsoft have no telephone numbers for me to call and it is extremely hard to use a small tablet to try and fix this.
