Amazon India — return of wrong product to amazon

Address:	Mumbai City, Maharashtra, 400050
Website:	www.amazon.in

I purchased crocs olivia II women's ballerina shoes from the amazon site on the 1st of july 2017. Following delivery i realised it was not the same product i ordered and asked for a return pick. The pickup was scheduled twice and no person came for it. After i rescheduled the pickup a third time for the 8th of july 2017 someone came and picked up the wrong package without informing or calling up two days prior to the scheduled pick. I informed the amazon team immediately and was assured that the package will be returned . However after 6 follow up calls and explanations to 6 different ppl i was told today on calling again that the item will not be sent back as it had been disposed off. I would like to know why this has happened after repeated assurances everytime that the item will be returned. Eveything about this item was messed up right from delivery to pick up. I am a prime member of amazon and have been ordering from amazon for a long time. This experience has been very unpleasant and the responding amazon team have been extremely irresponsible giving vague replies everytime. This has also cost me financially and my confidence with shopping with Amazon is shaken. I would like someone responsible to please get back to me on this issue as soon as possible.
