Poor service

I transferred money from my savings to cheque account yesterday before midnight. I checked and made sure it was reflecting before my debits went off. This morning my debit orders were reversed and bank charges charged per debit order. Call centre can see the transfer done yesterday but say nothing they can do to at least reverse the charges. On their side it apparently cleared today even though it showed last night. How is my account and the bank system different??? I chose Fnb because I thought they were the best, but clearly it's not about helping customers. It's about making money off customers. I used to promote fnb with everyone who didn't bank with them. I even made my husband change to fnb. I can guarantee the opposite going forward.
