Welcome to our community and thanks for posting. Sorry to hear you're having issues trying to re-set your online account password. We understand the frustration caused when you just want to get online.
Can we ask if you have tried using a different web browser and device to try and log in and change your password? We also recommend clearing any history and cache as this sometimes helps in this situation.
Please can you try the above and if you still require assistance after trying this please come back to us.
