Enterprise Banking Collections

We are a Business Enterprise Banking Customer, our Collection Debit did run on our clients accounts on the 1st. I have proof that all collections was authorized. Now its a limit issue? When all was fine when I authorized. I applaud our Relationship manager, 4 hours on the phone with Tech. Now Developers needs to fix it, but they do not work on weekends? No one on standby, this is so ridiculous, in that position, some needs to be ons standby?
