I have a 1.5 years old case where in I purchased a cat-6 lan cable (50 metres) from ebay seller epresent (Ajay Patel) of Bangalore.
I hope the seller epresent (who's Ajay Patel) is dealing with selling of products on a regular basis in order to make a living of out it and it is not a solo sale deal by an individual seller. Note that the cause of action (the first date on which you raised the dispute) and filing of the case should be within 2 years.
However on receiving the cables I found that unless the length of the cut portion is less than say 10 feet you cannot get a Gigabit connection, otherwise the connection remains limited to 100 mbps only.
Was the any agreement between you guys that the cut will be of certain length? Was the product against the specification of what the seller intended to sell?
So a lot of email exchanges via ebay's messaging (all of them are still saved in ebay account with a copy in gmail) where in the seller finally replied that I have to send back the cable which I did at my own cost. After sending the tracking number of the courier finally they responded that they will process the refund, but till date they have not done that.
Since the seller has asked you to send back the cable and he will make the refund, it is implied that the seller has accepted his fault and that is why he was ready to refund you the money. Here, your case is strong.
Do I have a case?
Can I claim only the expenses bourne by me or any additional compensation for the harrassment?
It looks like you have a case. You can surely ask for refund + cost incurred for sending the cable back + compensation from the seller and for that you can send a notice (by yourself or through lawyer).
If the seller does not pay, which I think he will not, you will have to file the case before the Consumer forum. The seller is located in Bangalore, and you in Calcutta and hope you make the purchase in Calcutta, so you will get the jurisdiction of Calcutta.
