Unable to speak to an operator

I need to sort out a problem with Mobile Wi_Fi app on my cell phone that is supposed to communicate with my router.When i try to connect from my cell phone the app tells me the LAN domain has changed. When I check my pc and go to the mobile wifi page and check the LAN domain and enter it on the app on my phone I still get the same message and cannot connect. When I call the vodacom call centre one cannot get to speak to an operator. I then try the smart Bot but it is useless. When i explain my problem the bot goes off in a completely different direction. I need to speak to an operator
