Reliance Digital — delivery not 24 hours, iou points not showing

Address:

Bangalore, Karnataka, 560092

Dear team,
I purchased samusung led 4k 55 inch tv from reliance digital store shahkarnagar on 4th of september, as discussed with the team i asked them to deliver it in the second half of next day the sales girl agreed and even her manager as well, but out of blue moon delivery guy called me around 9am and said he is out for delivery, there was no one at my place and i requested him to come in the evening but he didn't deliver it there.
Next day when i made much of noise in the store itself then only my tv got delivered and after my repeated request the installation guy came at 9 pm and installed it.
Reliance digital claim if your delivery doesnt happen with in 24 hours you can claim a gift voucher worth 5000, but when asking them they are not giving it to me, i am continuously writing to them for past 15 days or so but still no result.
One more thing i got a message to redeem my iou points but when i check my bill it is not there - cheked in another store then only came to know about this. Big fraud with me.
I feel cheated in through out the process, please help me in best solution of the same.
Reliance digital needs to improve upon customer experience else they will loose business.

Regards
Jitendra s
