Bad service from Makro/ Whirlpool

We bought a Whirlpool washing machine from Makro, Vanderbijlpark. Still in warranty, the machine started making a funny noise & staining the clothes. We contacted Makro & they informed Whirlpool. After my husband had to constantly phone for feedback on when they will attend to the problem? Then they promise that a technician will call us...then my husband followed up on when the technician will phone. Eventually a technician came to investigate and said that he needs to order a part. The part was ordered and installed. Then the machine worked for more or less 2 weeks, before it started making the same noise and on the clothing there's small black pieces...not sure what that could be?

Apart from the frustration of taking my washing to a laundromat, because my expensive washing machine is again not working???

The sad part is how WE need to follow up all the time, because between Makro & Whirlpool they just comment on someone will phone you.
