Guys... here's a good news for all of you.
Mobikwik is actually allowing multiple transactions of 20k back to back. I didn't really check for more than 20k though. I did 8k+7k+5k+20k with 5 minutes by using same HDFC Platinum DC through same Mobikwik account. Also I did the transaction of more than 1 lakh in this month in total. I jave Full KYC Account.
So, there's no limit of 1 lakh per month and also no limit restriction of 20k per day per card as such.
What I could deduce from my experience that it's not allowing more than 20k per 24/48 hours probably once gou add a new DC for payment. But after that time period, there's is no limit restriction. If anything new comes in future, I'll update here.
