Ebay.in — Neither eBay nor Seller ready to cancel the Order

Address:

Chandigarh, Chandigarh

I placed an Order on 17th Apr 2015 in which at the time of placing an Order it was mentioned that product will delivered maximum by Thursday 23rd Apr 2015. However, on next day I have an discussion with seller on call and he said that the product will not worked for which I purchased it. so I asked him to cancel the Order. He said I have shipped it already. After waiting till Thursday(as mentioned on site at the time of placing an Order) the product was not delivered. So I contacted eBay support and they Guy (Sameer S.) told that I have to wait for next 7 days as per process. The Order was not shipped and it was packed by seller, so seller's responsibility is over. Its shipment (logistics) team will pick it and send it. I told him to cancel the Order he said we are not able to do it. Seller will cancel it. So, I send mail to seller regarding the status of Order, he replied that as you said the product will not be helpful for you so I have not shipped it. I asked him to cancel the Order, he said he is not able to do it. Order will be automatically canceled by eBay or you can contact them for Order cancellation. I am not able to understand below points 1. The Order was shipped or not shipped on next day of Order placement (when I called seller)? 2. Who is responsible for delay in delivery? 3 What is the meaning of displaying "Product will be delivered to you maximum by Thursday 23rd Apr 2015"? 4. Who is able to cancel the Order Customer / Seller / eBay team? 5. What is the resolution to this case? Anyone, having any clue or knowledge will be of great help. Thanks Sushant
