Cheaper at Game

We went to Makro Vaal yesterday and bought a Samsung Toploader washing machine. We wanted to go to Game but the Salesman told us they are the same company. When we got home, we saw that Game is R300 cheaper with the same machine. We went there today and the Manager refused to give us discount. He told us, with an attitude, to bring the machine back and they will credit us. We already used the machine and they want us to drive up and down. Their aftercare service is horrible. No care attitude.
