Poor customer service and refusing to assist further

After settling my loan and being told that it will take between 5 and 10 days for my documents to be couriered; I contacted them yesterday to enquire why, 20 dats later, I still have not received my documents. I had provided CLEAR instructions as to what the courier company would need to do when they arrive at my residence, after which I was assured that I will receive a call from them prior to delivery. After enquiring about the delay, they rep**** saying the courier company showed up yesterday but could not get hold of me. I had no missed calls on my phone and for that matter no call PRIOR TO delivery to arrange, as they had promised. MFC’s answer is that I must contact the courier company... So in spite of their lack of attention and inability to convey instructions clearly, they are now washing their hands and it becomes my problem. No proper customer service and offering to assist, just tells me to contact the courier company and “trust you will find it in order.” No! It is not in order at all!!!!
