Vodacom fibre configuration drains my ups after 40 minutes

I took out a fibre with Vodacom and Vumatel in January 2023. it was a switch over from Openserve and Cell C.

I had a ups that powered my previous setup during loadshedding. My previous setup would last for the full 4 hour period when required. I then switched to the Vumatel/Vodacom setup and discovered that my ups would only last between 40 minutes to an hour.

I originally thought that my ups had become faulty and I probably would need to replace it. I then tried the ups on another none Vodacom configuration and discovered that the ups lasted the full 4 hour session.

This indicated to me that it was not the ups at fault but the Vumatel/Vodacom configuration was drawing more power than the other.

I conveyed this to Vodacom and logged a Service Request. After waiting 2 weeks with no response I called them again to enquire regarding the status of the ticket. I was told that as far as Vodacom are concerned the router and ONT are working and the ups issue is not their concern.

I asked the customer service rep to get a technician to come out or give me a call. I am still waiting.
