Bad after sales service with Lenova and Vodacom

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 could not switch it on. I took it back to Vodacom Wonderpark the next week and they advised that they will send it to their repair centre in Centurion to confirm an Out of Box failure. A week later they call and say it needs to go to Lenova for them to confirm. Since then I have been calling Vodacom for updates and everytime they advise that Lenova is not responding and and doing a credit as Vodacom requested. This is a very bad partnership and it is sad that the customer suffers in the end. I will also be writing a complaint about Vodacom as their service was just as bad.
