They fail to retrieve money that I send to wrong number via money mobi wallet, the number is not working and they can see the money is still there but they say they can't reverse it I'm so stressed, now they tell me about term and conditions which they didn't tell me about when they told me about this app, now is my problem, I cant wait for 30 days what if that person withdraw that money, all I need is for them to reverse it, how can u install something and tell me your not allowed to reverse the money, it shows they don't care.
