Horrible Customer Service for Out-of-box failure.

Purchased a Lenova M10 Tablet from Vodacom in Wonderpark Mall, Tshwane North, on the 6th of November 2021. It was not able to charge and I could not switch it on. I took it back to Vodacom Wonderpark the next week and they advised that they will need to send it to their repair centre in Centurion to confirm an Out of Box failure. At this point I requested to cancel the contract as I was unhappy that they refused to give me a new tablet. The store manager advised this was not possible as it was not Policy. A week later they called and said it needs to go to Lenova and Lenova needs to send confirmation of the OBF. Since then I have been calling Vodacom for updates and everytime they advise that Lenova is not responding and doing a credit as Vodacom requested. I signed this contract with Vodacom 2 months ago and I have not received my working device and service. Vodacoms relationship with Lenova is not my problem as I am Vodacom's customer. I am so tired of complaining to Vodacom, I even sent a mail to their complaints department (from: Poovendren Govender <***> to: *** date: Nov 24, 2021, 4:28 PM subject: Vodacom 4U Wonderpark OBF) and no response. This is pathetic service. Could this contract please be cancelled and whatever I paid so far be refunded. Clearly this is not how good customer service works. I will also be writing a complaint about Lenova as their service was just as bad.
