Bro, some people find it hard to shift to other mediums for same purpose while some hesitate to share their details here, there and everywhere. I am also, to some extent, avoid many options and stick myself to established and known ones where I know my mobile number won't be used for promotinal calls and purposes. Many don't care which app is it and just are after reward they get. Till now I have used HDFC BillPay and Unipay (before DC got withdrawn). Now moved to JioMoney (or Jiofinance) only after Unipay gone. Surprised that all my txns done via JioMoney wallet in 2017-18 were there including billers. Canara Setu, just tested with one payment. If Axis Bank allow this, I will never use their site/app as they make calls anytime of day. Beside these 3 working now I won't shift to new one even if all remove DC options. Main concern is for HDFC CC only because for other cards HDFC BillPay is enough.
P.S: I am having issue transferring wallet balance from Payzapp wallet to another Payzapp wallet. Did it stopped many years ago or I am not able to get how to do Payzapp to Payzapp wallet tfr using mobile no. like before. Payzapp to Account is available in Payzapp Card details Menu option but Wallet to Wallet is nowhere to see.
