Impossible to reset wifi password

I made a request to rain to get the info that enables me to manage my wifi connection. I am disappointed that I had to go through the process of completing an indemnity form but only to find out that it was a waste of time because VOX does not have access to the router in order to manage the WIFI connection. I am now stuck with a compromised wifi connection and Vox are clueless on how to update a simple wifi connection password
