[Resolved]  Ebay.in — Dishonored Rs 250.00 discount coupon

On December 19, 2009, I purchased a book 'All about Six Sigma" from ebay.in (Paisapay ID: [protected]). I had a discount coupon from them of Rs 250.00. The total cost of the order was Rs 329.00. I redeemed the Rs 250.00 coupon and paid just Rs 79.00. On December 23, 2009, I received an email from ebay that the ordered item was not available and they have initiated a refund of Rs 79.00 I had paid. I raised the issue that since the order was not cancelled by me but was cancelled at there end as they were not able to procure the item, I should get the Rs 250.00 discount back. They created a case (Case ID;[protected], to look into the matter. After 6 days I receive a email from them that I have been given a 10% discount coupon instead of the Rs 250.00 discount. This means that if I choose an item of the same value Rs 329.00, I will get a discount of only 32.90 with this 10% discount coupon instead of the Rs 250.00 discount. When I called them up over phone and over chat, the only explanation they had was that it was there policy. My questions are:

1. Why was an item advertised on the Web site that was not available.
2. Why no clause on the web site that in case the item is not available, the discount would expire.
3. The order was cancelled at there end and the discount was forfeited. So why should not I receive the discount.
4. When, I asked the customer service agents to give me the contact details of someone at the executive level to look into the issue. They refused to give me any details.

Kindly look into this issue.
