I got the product on 19.05.2018, with in two days i requested for return and they accepted my request and i sent all items what i recived and they received it on 28.05.2018. I paid 47000 through bajaj finace emi but they are not refunded the money as of now i. E22.06.2018. They are saying all non sense as they are technical issues blah blah. I am calling no of times day by day but there is no progress. How many days it could take to cancel emi? Is it more than 25 days. Totally fraud one
