Consumer Redressal

My order No- Kaun/T128779.. I ordered a mobile from kaunsa.com 8 months back. But the product was not dispatched for 2 months. On contacting them i got to know that they don\'t have that product in there stock. So i raised a complaint against refund for amount to them on there website. further they replied that they cannot refund but will provide a voucher code for buying few products. Later when i try to redeem that voucher,it failed. Again i wrote a complaint to them they replied- the product which you ordered our seller was unable to provide you due to shortage problem,you have to select any other product. I tried this for too many products but still the same problem exists.. Its enough for complaining them because they lack perfection.. There are maximum complaint against this website but how they are still able to run there website.. I wrote them 42 times for a single transaction.But they dint nothing helped and there contact no is of no use as no one pick up the phone..
