Unhappy Customer

I am very unhappy with the service I received from On Air I hardly have this decoder for three weeks and want it cancelled, however I was told I can’t do so after I advised the consultant I wasn’t told that I am bind to a contract as I thought it’s DSTV and they knew my decoder is old I needed the new one I thought I am renting it for 24 months. The first payment didn’t even go off yet and I am not enjoying it 😡😡😡 do you even consider customer services and the importance there of??? I don’t want the explorer
