Bad service

I asked for the second contract with Telkom in February 2024 which is a router that I am using at Soshanguve xx.Before I opted for router I asked about a Fibre and I was told that Soshanguve doesn't have.I told the consultant that I need a router that will accommodate 28 people and she advised me of that router and the speed.She told me I am going to get the router that has aerials,when I went fir collect it was a disaster whereby I had to wait for an hour for the router and I told to leave,they will call me as they don't see my router. Ok I went there ,the following day i went without call I was told that the router with aerials is out o stock they have a normal white router. As a frustrated client I had to take that router as students needed to connect. I am so angry because my students have been complaining and I thought maybe it's network until I use a different network and it connect. I need to cancel this contract with immediate effect as I believe the consultant wanted sale ,but not putting herself into customer's shoes.
