Failed reversal of ewallet and even renewal of pin of ewallet

I am.an fnb client and am disappointed in the way FNB handles ewallets..I sent an ewallet that the receiver didn't collect within 16hrs and a week later when she tried to renew the pin, the system didn't let her yet fnb had sent a notification to the receiver reminding her that she hasn't collected the cash..now my predicament was that reversing the transaction was also impossible on my FNB app..am disappointed with the fnb ewallet service..I have tried all their call centre and all options suggested on reversing and nothing works..this is very unpleasant.
