Disgusting after-sales service at Cresta Game

I recently bought a HiSense washing machine from Game in Cresta. After 3 weeks it stopped draining. I've spent over 2 weeks phoning and emailing and no-one has been around to fix the machine. I spoke to the manager at Cresta who assured me that the agents would call and arrange for the machine to be fixed. Still nothing. As you can imagine, it has been so frustrating - imagine, no washing machine for 2 weeks after spending money for the convenience of a new machine. I will definitely think twice before buying an appliance from Game. I emailed/spoke to the following people: ********** - 3rd April & 4th April, Sasanga Buso ********** at the call centre - 4th April - sent 2 emails Petrus Sibonda at cresta- ********** - 5th April and each day since. He assured me that the supplier would contact me, still nothing.
