Not collecting tablet

On the 13 of July I received a tablet from Elite Mobile and this tablet was not charging at all. I phoned on the 14th to ask them to collect the tablet on which I was informed to take the tablet to a Vodacom dealer, which was done the 15th of July. Vodacom confirmed that the tablet is not in working order. On the 14th of July I sent an email to Elite mobile requesting them to collect the tablet on which they rep**** that it will take 14 days. I phoned Elite mobile on the 16th and the person said that the tablet will be collected within 9 days. I have phoned them again and send an email to request pickup for this faulty tablet and the only response is that the 14 days are not up yet. 14 days are definitely up and I do not want to pay for a faulty product and has requested them to cancel the contract, on which they said that the contract will be cancelled by Vodacom if it is back in their warehouse. Vodacom is also useless as they will not take responsibility for the tablet as Elite mobile is the seller but Vodacom is the service provider. Please collect this tablet and cancel this contract as the tablet is not working. Pathetic Service from Vodacom and Elite mobile.
