ACT BROADBAND
Refund not received

I was owning an ACT Broadband Internet Connection and decided to cancel the connection on 1st October because i shifted the house to Bannergatta Road, Bangalore where this internet provider is not having feasibility.

There was a refund of Rs 494/- against the security deposit which i have made. I tried reaching customer care through mails and calling them directly several times. They are telling that DD was sent to my address on Nov 03, but still i have not received it. There is no response from their side nor replies.

Please help me out to resolve this.
