Amazon India — return pick up not done even after initiated for 3 times in 12 days

Website: www.amazon.in

I have initiated a return pick up in amazon for my order #[protected] on 23rd august. The pick up was scheduled on 24th but nobody contacted. Neither i received any notification on any reschedule or cancel pick up.
I cancelled the return and initiated again on 29th august. I contacted the customare person and was told that the pick up would be done for sure.
But pick up was not done on 29th also. I had to contact customare care again and explained the problem. She told me she will create another one and this time it wil happen. Its been 48 hours now after 3rd was initiated. But no status no return pick as of now.
It's really frustrating with amazon now. Worst experience ever.
Kindly resolve this.
