Poor customer service and deceptive methods used to make a sale

I subscribed for the Telkom LTE uncapped package with DSL Telecoms. Before the subscription I was assured that their support team will be there to assist me whenever I run into any issues. At first I was reluctant to go for it knowing how bad telkom technical support is. But DSL Telecom assured me that I will be dealing with them when it comes to support. Now that I have subscribed, whenever I call them to assist me with technical support related issues they don't even entertain me. They quickly become dismissive and ask me to call Telkom for any support related issues. Now I am sitting with a 24 months contract that I am not even using. This is really frustrating and unfair treatment from DSL Telecoms and Telkom.
