I have been victim of them, as I have been fooled by them making my money waste.
There are online recharging and online payment platforms and among them the worst experience I received is with oxigen wallet. One day received an notification than 20% cash back on recharge of 500 then I went to recharge hen it said that on one atm card the the offer has been availed on this atm card and then I used my another card and recharged 500 rs but till now I dint receive cash back though I have fulfilled all the conditions for getting of cash back.
I didnt receive so from then I stopped using the app as its worst. sometimes why I dont while recharging it says connection timeout that which makes me irritate and stopped using it.
Its app is also waste. hangs all the time. Its my suggestion to all to not to use this site,
