FNB Business e-wallet

I have been at the Table Bay Branch 3 times to try and resolve an error message in order for to access an e-wallet. When I dial *120*277# I get an error message. It's says An error has occurred on this transaction. Please try again later. I go to the branch, they put me on the line with e-wallet dept. No one can assist. Instead they refer me to my network provider. I go to Cell C they also claim that everything on their side is fine I should go to the bank. If this is an FNB product why can't FNB assist me. This is why I no longer bank with FNB. Completely useless. I wasted hours and money and still no result. If you sold a product and it's defective it's up to you to fix. I will not recommend any company to make use of this function to send money to clients or employees. It doesn't work!
