DStv wifi

I have a very bad experience with DStv WiFi , i received my WiFi router on Friday the agent who was assisting me **** about the charges that are liable to me , I asked her about the prorata she said it’s not there , I asked about any other additional fees she said there isn’t , and I asked about cancelling she said I only pay for 180 If I would like to cancel my subscription, now when I call to cancel because I wasn’t happy with all the fees I was being charged unaware they are telling me I need to pay an extra 2000 Coz it was a contract , now it’s a hassle trying to get this contract cancelled , take it at your own risk
