X box

I received the worst customer service from vodacom. I bought a x box in July at the vangate mall branch in Cape Town and within 2 weeks the product stopped working. I took the product back to the store and demanded a cash refund as I will not except a broken product which couldn't even last 2 weeks so imagine what will happen to this product in the next few months but the staff member said to me there's nothing he can do I have to wait and I can't get a refund.the customer service is so poor, A few weeks passed and I received no feedback regarding the product or any sign of interest in solving the matter. I was so furious after having several arguments with the vangate mall branch staff members saying THERE IS NOTHING THEY CAN Do, I then decided to visit other vodacom branches and explained to them an asked them if I can get a cash refund and if they can assist me and they said yes I can get a refund but unfortunately they cannot assist me because I have to go back to the branch where I purchased the product from. I even called the online services and recorded the call I had with them saying yes I can get a refund. I then went back to the vodacom store at vangate mall and told them what the others stores said and yet once again they responded by saying THERE IS NOTHING THEY CAN DO. It's over a month already and I'm still without the product or the refund.
