Reliance Digital — Money not refunded for cancelled product

Address:

patamata,vijayawada

I ordered samsung s6 lite tab on 6th june. It was supposed to b delivered in 3 hours. I have cancelled the order due to the delay in delivery. My order number is RDF12587255

Today is 15th june and I haven't recieved my refund. I have been calling every day from 10 days (more than 15 times) and they are not giving any solution. I have mailed them 7 days back several times and they are not even replying.

The store person saying he has cancelled order several days back. But the reliance digital is telling me to wait for sometime. And its been 10 days they are not responding to my mails.

The customer service also hunging up the phone without listening.

So if any concern authority could help me. I will be grateful.
