Telkom Customer Service

Yesterday I received a router from Telkom as I was planning on using their wifi but ended up not being happy with the package deal and wanted to change it. I went to the Telkom Branch at Centurion Mall and was told to cancel the contract (as they would give me another one) but would have to call the call center as the order was done online. I called the customer service and received the worst treatment. I spoke to a lady by the name of Laschen Ephraim who kept changing the procedure of how to go about the cancelation. We were told that there's a 7 day period where if you want to cancel, you can free of charge but Laschen said this was not true and that I would have to pay R800 + which makes no sense. I am extremely unhappy and fed up with Telkom.
