Consumer Redressal

Hello, I had booked a consignment from Hyderabad - Madhapur to Mumbai - Virar for relocation in 06/08/2013. At that time I was been informed that you need to pay the insurance amount of Rs.6270/- which will be refunded back once the consignment reaches safely to destination. But now I tried calling several times in there Hyderabad office on the numbers 040-65535247/9666457790/9000007280 but did not get any favourable response. I was always given some other numbers which offcourse did not pick up. Now its almost 2 years and I have not got any refund back. This is really not acceptable with such as DHL brand. So could you pleae look into this and get my insurance amount recovered.
