DO no DO business with them..i smell *****

I saw this app on the play store. I thought this would be a great service to use. Read everything about them online. Everything looked good. Nedbank are sponsoring them. On Their website its saying yout money is safe with them. I deposited money. Sent some over the weekend and when i tried to log onto their app. Boom account suspended. Not sure why. They did not call me to notify me about anythjng. Nothing. Even sent them emails. Nothing. Just silent... Please do not do any business with these people. Im contacting Nedbank today regarding this
