Reliance Digital — IPhone XR not yet received cashback

Address: Lower Parel , palladium mall

I purchased iPhone XR on 28th oct 2019 and i was told that you you are getting discount of 5000 on your HDFC card and 2000 from the store as there was some offer available frok relaince that time ... and cash back of 7000 will be posted in you account within 120 days ... as it’s going to be 1 year in this month I haven’t recieved any cashback yet ... I already mailed all my problem to reliance digital customer care from past 4-5 months and they keep on saying that your cashback is posted in your account on 30th January but there’s no transaction of 7000 n I haven’t received yet because I spoke to HDFC bank and they replied that reliance digital has not posted any cashback in you account ... and even after complaining there’s no solution for me from reliance digital ... I want my problem to be solved within 2 days as I can’t wait longer than this
