Online Stokvel Account mess

I detest FNB. We have a stokvel with a bunch of ladies and FNB was chosen as a preferred banker (worst decision). We registered the new online stokvel account with them, I'm one of the signing members and happened to be the first one to be paid. Since yesterday I cannot accept the invite on *120*321#, an error "we cannot process your request at the moment, please try again later or call ***" always appears right at the end when you think all is well. Then tried calling that number since 08:30, it has been a fruitless exercise. No one knows about the online stokvel and I've been transferred from pillar to post still not assisted. I love the innovation but you don't train the staff nor properly update the after sales processes. We are now left to fend for ourselves. I'm still not paid, no assistance and no way forward.
