TERRIBLE SERVICE!!!!!!!

I bought an Astrum Bluetooth speaker on the 28th of August for R301 , Springfield Branch. It started to give me problems four weeks back It was beeping and keeps disconnecting when you are listening to music, then I took it to the store two weeks back and they booked it in for check up. I waited for their call and I got a call today and they told me that it doesn't have a problem. I told them what it was doing and I was using it for my modeling practice so I would not take back something home knowing very well that it does not work properly and they said they cannot help me cause it been three months but the warranty is six months. I have been buying from them for two years but I never knew they insensitive when you not happy about their products. I am never ever gonna buy from them again!!!
