Change the pay-off line - How can we frustrate you

We are a Methodist Church having Numerous accounts with FNB. For some reason, FNB has swopped and mismatched these signatories. When bringing this challenge to their attention, all we have received are promises to sort it out and no action. They sent us a list of documents they require to sort it out, which we have put together, we have told them that we are ready to come to them with this information, and they keep tellilng us they will let us know when to come. In the mean time, no cheque is being honoured because the signatures are' incorrect' and we therefore do not have access to the funds of the church. <br> <br> We requested a letter of apology in this regard, that was promised, but frustration is being delivered. <br> <br> We have also requested to migrate to online banking, however, this is not happening either, Please stop asking how you can help us because what we have experienced since December, is Frustration, not HELP. <br> <br> FNB - How can you Frustrate us so?
