Offered New Contracts as Upgrades

I received a call from Mondo in December to upgrade my existing Vodacom contract. A laptop and router were delivered in December. I was only able to have the time to do the activations early in January only to be sent from pillar to post by Vodacom one saying it was an upgrade and should happen automatically and another saying I should call upgrades department. I only realised when I received my invoice that I now have a new contract. I phoned Vodacom to query and I was told it was not an upgrade and they arranged for the pick up as I decided to cancel the new contract. 14 days later the laptop was not picked up I phoned Vodacom again and I was told I was due for an upgrade and it should have been done as an upgrade so an upgrade was done however the other laptop has not been picked up still. When I called Mondo I was told they will not pick up the laptop as it was already after 14 days of delivery. I phoned back Vodacom as I am their customer and Mondo got my number from them I was told I needed to call Mondo. I have phoned Mondo again and they have said they will listen to the call made by their consultant to hear whether I was offered a new contract or an upgrade. I was promised feedback within 7 days. I have not received any feedback 10 days later and my attempts to call their customer call centre have failed. I paid for 3 contracts in January and by the looks of things I am going to pay for 3 contracts again end of February. I am more disappointed in Vodacom as Mondo got my contact details from them and they are now distancing themselves from the matter but still charging me.
