Im really sorry to hear you are going through this! I had the same happen to me, but then i realised the passwords were different and luckily I took a pic of my original first password and it worked, but i was locked out for a week! I hope they will help you to sort this out, because I know how horrible it must feel :(( I've been in your shoes!! Good luck xx
Thank you, @allasyummyfood. It's crazy making at its finest.
