Lack of service and passing the buck

I purchased a Samsung washing machine in March 2015.Abt 3 wks later the machine started staining my darker clothing. I first resorted to trouble shooting as follows: eco tub clean,changed washing powders, used liquid detergents,omitted fabric softeners etc but to no success.The machine continued to stain. I then contacted the store who logged a call with samsung, but the lack of service or poor service started here. They called me once and did not get hold of me,left no messages or sms to notify of call.Eventually I contacted Samsung spent 20 min from my cell to solve the issue. A Techi was dispatched a wk later. The Prolad techi then guided me again as to how to use my machine, but after that Eco tub clean with the dishwasher tabs the machine now prompts a weekly eco tub clean ?A full month passed where I had no feedback from Samsung. I took onus to follow up on the call , I learnt that Prolad logged a call to have the machine replaced and that Samsung did not inform Prolad of the outcome! So I called again and after a lengthy call my from cell AGAIN, was advised by Samsung that I should re-log another call as the previous call logged not longer applies No reponse to date!
