Subpar customer service- Nobody knows which department does what

I settled my 2 loan facilities on Friday. The debit order went off the Saturday yet my account is settled and closed. I called in on Tuesday trying to obtain a refund on the amounts that went off my account. I have been sent from pillar to post, each department washing their hands and I still havent been assisted and got my money back. All of the below numbers were transferring me to the next department until I had a whole argument with the last agent regarding their lack of knowledge of who does what at their call centre. ****** ******

I just want to be refunded as I know the branch is as useful as the call centre! where is my money!!!!!
