Vodacom Wifi is not the best.

I entered into a 3 year contract with Vodacom which includes a wifi router with 50 Mbps speed sometime in September 2024. They assured me that the area I live in does have coverage and that I’d be able to even connect up to 10 devices with the same speed of 50 Mbps. For the first 4 months the speed was perfect but then after that it went as low as 10 Mbps even less. I’ve went several times to the Vodacom branch in Greenacres and they’ve done a network synchronisation, even allegedly took it in for repairs and it came back with a report that it has no problems. Till today Im still getting less than 10 Mbps which is not what I should be paying for. Every month they debit R450(which is not what the agreed amount is which is R400) but I’m not receiving the 50Mbps speed that I should get.
