False Information

On 23 March 2016 some Guy phoned me to do an Upgrade/Change to my current 1 Gig Data Contract to a 2 Gig Data Contract. A Few days later they delivered a new WiFi Router and new sim. Upon phoning the customer care they advice me its a new contract and that i need to cancel the old one. And this can only be done in September when the old contract Exp. This was not my understanding and i don't want a new contract. The call center agent advice me they will collect the new parcel as we did not open it. This is now almost a month later, and no one has collected the parcel. And i now have to pay for 2 contracts. Can someone sort this out as i can not afford this.
