Voltas — Ac not working, part being not replaced since 1 month

I purchaes voltas window ac in april 2023, in may 16, its started showing error E6 amd not cooling, technician visit was on 30th may and they said outdoor pcb will be replaced and it will come in a week, its been a month now and i have called service center and voltas customer care multiple times, they are just saying part is not delivered and not taking issue seriously, my hard earned 35 k is wasted amd not used ac even for a month after buying, its peak summer and have to sleep without ac, what is the use of ac when summer is over, they should understand it and solve the issue asap, otherwise just take your ac and return my mone, i will go for some other company, big no to voltas, never recomment to anyone, even i will persuade people not to go for voltas, totally making fool of people, service no [protected]
