Extremely disappointed customer

I am extremely disappointed with the service I received from Vumatel in Newcastle, Madadeni. I have been experiencing ongoing issues with my Wi-Fi connection, which prompted me to visit the Vumatel office located in Section 2, right next to Spar. During my visit, I was provided with the contact number of a customer service representative named Noma. Unfortunately, my interaction with her was far from pleasant; she directed harsh and inappropriate language at my father, which was unacceptable.

After that encounter, I returned to the office for further assistance, where I was given another contact number to reach out via WhatsApp. I sent a detailed message explaining my situation, but to my dismay, I never received any response. In a bid to resolve the matter, I attempted to call the given number as well, but no one answered.

I find myself in a frustrating position because I have already paid for the Wi-Fi service, yet I am unable to access it at home. I need guidance on how to proceed from here, as it feels like my concerns are being completely overlooked. What steps should I take to ensure that my issue is addressed and resolved promptly?

Regards,
