First and last Samsung purchase ever!!!

I have been trying to resolve my issue offline, but for 3 weeks it’s been going nowhere so this is my last resort. I bought a washing machine on the 25th Mar just before lockdown started and since I plugged it in it’s been making horrific noises when washing clothes. I spoke to someone the day it happened through the online chat support, did all the troubleshooting and it didnt resolve the issue. I was told to hold off until lockdown ends to take it further. When we entered level 4, i spoke to agents and they said that they are able to assist me. I have been waiting 3 weeks since then to have a technician asses the unit. The first call to your Tell Us, i submitted all the details and was told someone from your home appliances will be in touch, waited a week with no contact. I phoned again and was told my query was never even logged, so had to go through the process again. I was told it would take about a week for someone to be in touch. I got a call the next day to send my proof of payment to their whatsapp number which i did immediately after the call. Yesterday I got a call, another week later that they haven’t received it. I checked the number and message sent and it was never even read on your side. Your agent said they will sent a mail to get it again, another day later... no email?? ***? I’m so irritated with your service, I want this sorted on ASAP. As per CPA I’m entitled to a replacement machine if defective within 6 months, I logged the issue with Samsung on day 1. I dont know if you are trying to run out the time so you don’t have to replace my machine, but I’m done waiting now. I want my replacement this week. My first and last Samsung purchase!!!!
