Poor products and service from Vodacom

I took out a contract with Vodacom for a tablet.<br> The tablet did not work and was sent for repair.<br> I was informed that there were too many issues and the tablet would be replaced.<br> The tablet was replaced with a 'refurbished' one, which also did not work.<br> I now have no tablet and it seems have to wait for the 'refurbished' tablet to be repaired.<br> The service department at Gateway Umhlanga do not EVER answer the telephone.<br> I do not see why my tablet which I had for less than 6 months should be replaced with a 'refurbished' one.<br> This means I am being given someone else's faulty merchandise.<br> The service I have received from Vodacom and from the branch Chatz Cellular in Hillcrest is appalling,.
