Fnb ewallet so hard to access why

FNB ewallet service is the worst. I receive ewallet message at 20h00 and few minutes later I try to withdraw the money, it says I must request a new temporary pin. How is that possible when the pin that comes with the message is supposedly expiring after 16hours??? Barely few mins after receiving the message/ and pin then I must request another pin. Worst part of one doesn't have airtime they can't even receive that new temporary pin. Even if it's advanced airtime the service doesn't allow one to receive a new pin. What an inconvenience of a service. Honestly this is very poor from FNB I'm never using their ewallet service again. Please learn from other banks how convenient this service is meant to be. I have never had such ridiculous issues from Capitec, Standard Bank or Nedbank. You get your instant money or cashsend immediately without pin issues. As long as the money is sent to my cellphone pls make it simple for me to access my money. Someone maybe be stranded without airtime but can't access their ewallet. Really disappointed with this Fnb service. Worse part why does it want me to get another pin when the original hasn't expired. I'm never using this service ever again, worse part I go to a branch I'm being told I need to get ewallet card coz I use ewallet a lot, when the consultant tries to issue me with the said ewallet card, the error message is that I can't get the card coz I have an account with them. Aiii not this is a joke and very very poor service, such a huge inconvenience to access my money. I will use other bank coz this is really poor from FNB... disgruntled customer
