Universal Laptop charger faulty appalling service

I bought a laptop universal charge for R650 on the 27th of November 2017. On the 7th of December 2017 the charger stopped working . This made the item only 10 days old(This is including the weekend) and is no longer functioning. The manager said they need to send it in for repairs and that might take till next year or I can buy a new one. Really !! What am I going to do with two chargers and if I bought another unit whats to say that one will not do the same after a week and I waste my money once more. I am appalled by the customer service and I will Never, I repeat Never deal or advise anyone to support or buy anything from Matrix Warehouse again. Rather pay more and get service and quality that you can rely on with a decent attitude and not just the generic reply's they give on hello peter as I read in other similar reviews. Oh well I suppose its not there problem. That's the attitude Matrix has.
