Delivery of wrong device (Ref Nr: 54886)

On 30/3/2015 I was contacted & offered a contract for a wi-fi device. Received delivery from RAM on 2/5. Upon opening the parcel I realised that the wrong device were delivered - Vodacom Smart Tab?? I immediately tried to contact Vodacom (telephonically & via e-mail) & since then made so many calls & have spoken to so many people at different departments regarding the collection of this wrong item. SIM card has been activated, data missing & I have not even opened anything. I also requested for this contract to be cancelled (it was indicated to me that the contract can be cancelled within 14 days). I spoke to Davisha (& Hilda from Vodacom) on 20/4 and I was promised that the parcel would be collected. On 11/5 I e-mailed customer services (Mondo) and Sasha Lee confirmed that she would arrange for urgent collection. I made a follow-up again on 18/5 and she promised again that it would be escalated for collection & cancellation of the contract. E-mail on 19/5 to Sasha Lee - no response. RAM contacted me & promised to collect on 20/5. I am still waiting for this parcel to be collected. In the meantime I am billed for this contract and cannot get any service from this company.
