Dear Aniket,
It seems you are talking about your purchase on an international eBay Site. In such cases, it may take 21-35 working days to deliver the item internationally. OTB means 'On the Board' or in transit. For more information, I would suggest you to please contact your seller via eBay messaging system and am sure that he will help you to track the shipment.
i dont think it reached India when it is showing OBT. be little patience and allow 5 - 10 more days and then open a case against your seller through PayPal . you will definitely get your money back or the product you ordered
I regret to say that but since you've purchased it on an international eBay site, I can not comment on. Had checked with the courier company at your local or even your seller can check with them.
Are your referring your transaction for PaisaPay ID: 32312060692? If yes, then I would like to tell you that online tracking shows that the product has been reached at Gulbarga. You can track the same on :
