refusal of payment

i purchased a sewing machine(easysew) for about Rs 3000, in november 2014 which i returned it since the product send to me was not the same as shown in the advertisement on TV. In return they send me the same product again and on 17th december i again returned it with the same complain of unsatisfactory product and not the one as shown in TV advertisement and since then i have not recieved any correspondence till date. i also gave a call to them about 10 times at various intervals at which i was assured of an early response but with no action thereafter. still waiting for any response
