Consumer Redressal

I had took my transcend portable hard disk 1TB for warranty/replacement on 17-july-2012. The same is not received by me till date.There service center at delhi had wind-off there office namely Accel Frontline Services Ltd.They dont even respond to my mails.Please note the model no TS1TSJ25H2P & the s no. 4303770360 .CALL ID : TSCBFJ120002274DW DATED 17-Jul-2012.The fault with it was too minor, just a loose usb slot which could be repaired in 5min if done locally .I did not want to void the warranty ,so I went for its service center in Delhi which is 600 km away from my home place. I am continuously mailing transcend`s customer care from last 5 months but there mails have been full of excuses like ready for transportation, out of stock , in process , contact accel etc etc.They dont even tell how much more time its going to take. It has been more the five months and I still don\'t know what s the status & when will I get the disk back.
