SADV took my money and Not provided network access to me

I paid my (VumaTel) wifi subscription on the 28th of October 2025 and I was fully connected on the 29th, since then I dont have connection and I reported this to Vuma and they told me to contact SADV since they are the service provider on my account, I'ts been 2weeks now and still no connection but I've been sent from pilar to post with no promise to compensate for my wasted money and time.
