Unbelievable

I have 4 routers for WiFi for my business and home 2 of the routers are not functioning since last Vodacom sends me left and right meanwhile I’m being debited every month, I don’t get their new method of operating I phoned Vodacom, they authenticated me already and for them to send a technician you have to approve it via email which first it stupid, no one told me about I just can’t believe this
