Frustrated Customer

in June of 2018 I took a laptop contract with Telkom , the contract was for a laptop that comes with a router and 1 gig data bundle a month , however till this day i cant connect to the internet and I went to the store at Mall of Africa twice and the second time the store supervisor assisted me by changing the Sim card of the router and said I must wait and use it the next day and when I used it ...it was still not connecting , phoned the call centre they could not assist me instead they told me to go to one of their stores.

I'm frustrated with telkom and i want to cancel this contract because .
