Consumer Redressal

Bought intex aqua i14 mobile from Tohana on 19-7-14. Deposited in service centre at Sirsa on 9-9-14 due to malfunctioning. Company has not repaired/replaced till date, rather providing a new mobile with lower specifications, whose acceptance refused by me. Have contacted them several times, but no solution has been provided till date. Have called them 10-15 times, each time for several minutes (10-15 or 20 minutes) their no. That is NOT toll free. I was Mentally harassed by unsatisfactory response of them. Had to temporarily use a personally procured cheap mobile for several days, which rendered me unable to access mail/Internet services. Ultimately, had to purchase a mobile of another company, which cost me much. Filed Complaint with core.nic.in on 12-10-14, but no resolution has been provided till date. Please help me. Kindly provide me a resolution as soon as possible
