Reliance Digital — can't, deliver cant refund!

I had extremely bad experience with reliance digital in juhu. Wanted to buy a laptop which initially they said will be made available in a couple of days. When i went to make payment, i was told it will take 7 days max. On the price, i was told one price when i went to the store, but when i was at the cash counter, the price was increased by 4k. Still i said i will go ahead, thinking it was a genuine mistake. Made a full payment. Was following up regularly in next week and even on the day prior to delivery day i was told i will get tomorrow afternoon. But on the day of delivery i called and they said it is out of stock and will take another 11 days. This was really not acceptable. The product was in hyderabad warehouse so i said you can get it in 4-5 days, i can wait for that long, but they didnt show any interest. I was given option to wait for 11 days or cancel the order. I went for cancellation and was told it will take 8-10 days for refund which i feel is too long. And now it is more than 13 days and still there is no refund. They are giving lame reasons for the delay, and saying it will take 4-5 days more.

Really lost all the trust in the store. They just wanted to overcommit without any backing.

They are not showing courtesy to update also, even after me calling multiple times. They just say they will call in 2 hours and never call.
