Poor products and service from Vodacom

I took a 2 year contract on a Vodacom Smart Tab 3G at the end of August 2015 through Vodacom Chatz Connect in Hillcrest. The tablet was painfully slow, kept hanging and generally did not function well. I took the device back to Vodacom Chatz connect for repair on 26th February 2016. This was within the first 6 months and still under warranty and was sent to Vodacom Repairs in Gateway Umhlanga. I was informed by the store owner at Chatz Connect in Hillcrest that the device had too many problems and would be replaced. I received the replacement and found this to be faulty as it would not switch on or even charge. <br> I returned to the shop and requested a new replacement in it's original sealed packaging and was told that I would not receive a new tablet, only a refurbished one. <br> It seems I am being fobbed off with second rate products. in addition, I am paying monthly for the device, which I have not had the use of for the past month and on it goes.<br> When I took out the contract, I expected to have a device which would work effectively. This device was faulty and should have been replaced with a new one. <br>
