L ordered product but i received completely different product so i requested a return and customer care said the product will be picked up on next day. But no one came for the pickup so when i called the customer service they said it that the pickup will be initiated on next day but no one came. I have called many times but they say next day it will be picked up but every time i got unexpected response. I called 6-7 times for pickup and than on 5th pickup product picked by pickup executive. Pickup boy was also satisfied by the returned product. He also called amazon service executive at the time of return pick up. Amazon service executive was also satisfied with that product. Amazon customer care executive name was aniket thats pickup boy told me this.
After confirmation from amazon service executive, l have returned the product.
And now they even blocked my account. Many refund already pending and also can't able to order new products. I'm facing many problems after all this # action.

Wow, whats terrible service amazon are offering. This is really cannot be expected from amazon. Kindly refund me as soon as possible and unblock my number i have also amazon pay balance.
It's a shame that amazon's standard have gone down that your customer care people are not able to resolve such simple issue.. (Lt is amazon. I had a much higher expectations from it).
