OneAssist Consumer Solutions — Oneassist is taking more than 48 hours to verify documents

I have raised a claim last Friday (Nov 25) as my device's wifi was not working without any accident and I want to get it repaired as well as replace the screen which has a scratch.They are calling me 2-4 times a day without making any progress in claim since today where as one assist portal says it can take 48 hours maximum to get it approved.Why oneassist is lying and frauding customer? Last time also they have asked for 18k from my pocket to repair my device saying insurance provider rejected it whereas service center repaired it for free.
If needed I can raise this to consumer forum as I have all the call records in place how oneassist cheated me last time and trying to cheat me this time also.Please give me a proper resolution with compensation
