Telkom Breach of contract

I Wrote a previous report regarding my contract i took out with Telkom, It was a contract that gives me 10 Gig data during daytime and 10 Gig night owl.

They advertised the contract with a wifi extender, after the first complaint they said they will send me the wifi extender or arrange for delivery.

They just stopped with the communication and no wifi extender was delivered as promised.

Can you please cancel my contract as i do not want to do business with people that promotes false advertising.

I know of other customers that has the same problem with telkom so i can staff my complaint more than once.
