Makro centurion tech terrible quality

In the last year iv purchases 3 pairs of headphones and 3 usb speakers from makro centurion,,each time the floor salesman sells me on a certain brand saying it's good I buy it and go home,either a week or two or a month or two later the speakers sound starts distorting,the headphones break,the sound distorts,,I have gone back on multiple times to exchange and the process is long and tiring,then they swap it for a "better" model and that one breaks two weeks later..I'm sick of going back and forth..I have two broken pairs of Polaroid headphones first pair cost R399 cause it was the good brand then when they broke I didn't even return it cause iv given up I just went back and bought another pair of Polaroid for R600 on the 19th of the 6th and now the sound is distorted..becareful when buying tech from makro centurion
