Vodacom Makro Cornubia - PATHETIC

I took a contract from the Vodacom at makro cornubia on Thursday the 11/04/2019. I was told by the sales person i have 7 if there is anything wrong with the phone to bring it back and it will be replaced, The phone is now overheating and it is dying within an hour or 2. At NO POINT was i told that it will take 7 WORKING DAYS for them to assess the phone and then make a decision as to whether i will get another phone. Firstly this phone was a gift for my mum who's birthday is tomorrow, secondly my mum cares for my kids and she needs a pone at all times so i can get hold of her for any emergencies. Thirdly the sim card had to be changed to fit into this new phone so now my mum is sitting with no phone and the after service from the sales person is Pathetic. She just shut me down saying there is nothing she can do i have no choice and i just have to wait and not to mention that she is now insisting that she explained everything to me in detail which is a LIE. This is the reason i stopped taking contracts with Vodacom because their service and more especially their after service is PATHETIC. They behave as if they are doing you a favor somehow. Never will i take a contract from Vodacom.
