How much longer must i be messed around!

Trying to stop my debit order is a mission. Go to the bank they tell you call personal loans directly. Call them and they put you through to collections, from collections the fool transferred me back to the call centre! from the one person to the damn next!! The next person I spoke to had a attitude and when I told her I already spoke to collections she still insists but only they can help me with cash payments or settlements. I then spoke to another collection dep. person, there the phone just went off. now what else must I deal with, with this ***********, unhelpful people!
