Unable to cancel an unwanted contract!! Pathetic service!!

Firstly - you do not even deserve one star!!

My partner signed up for a home wi-fi deal. He was “sold” the contract by an MTN agent by a phone call. The agent advised that he had 10 days to cancel the contract and he would not be charged. When the router arrived we realized this contract / router was not going to work for our home set up. My partner contacted MTN well within the 10 days and nobody was interested in assisting him. He then contacted Mondo. He contacted this company too within the first 10 days. He was given a reference number. He was advised that the router would be collected and the contract cancelled. He has had to contact Mondo again and received a second reference number. The contract has not been cancelled and the router has still not been collected. To add to this, MTN has taken payment for two months for a contract that we are trying to cancel. And the amount is more than he was originally quoted for the contract. To add to this he is now being threatened to have his cellphone contract cancelled until an "outstanding" payment is made for this wi-fi contract. An amount of over R1000. A contract that he has tried to cancel for weeks, actually months. Your service is pathetic. All we want is to cancel this contract - and he does NOT owe MTN anything. MTN actually owes him a refund. Sort your s*** out. We both have cellphone contracts – and at this point – we are both going to cancel!! Please contact me privately so I can provide his details and reference numbers so this can be sorted out ASAP!!
