UNACCEPTABLE AFTERSALES SERVICE FROM SAMSUNG

I am writing to express my extreme disappointment and anger as it has now been almost full month since I reported my faulty washing machine and up until today it has still not been fixed, this is completely unacceptable from a big brand like Samsung, I bought a Samsung because I trusted your quality and your after-sales service but you have let me down badly, for a month now I have been unable to wash my clothes properly at home and it has caused huge inconvenience and extra costs for my family while I wait for you, I have called, I have logged a call, I have been patient and I have been given empty promises and no technician has come to fix my machine, I am very unhappy and I expect you to take urgent action now and send a qualified technician to fix or replace my washing machine within the next 24-48 hours, I need a solution today, not another reference number. they sent out a technician who claimed tat he fixed it but still the machine is not working i am extremely disappointed and demand urgent intervention to get my machine sorted out . this is not acceptable My reference number is ***. i have called the liptronics centre they promised to call me back in 30 minutes and now are completly ignoring my calls with no communication whatsoever. i need this resolved
