Title deeds in limbo

I have cancelled my bond with Nedbank as my property is been sold. Their customer service is great but they have used a supplier to courier documents and from the 23rd August to date the docs are not delivered to the cancellation attorney who is also following up daily.my question is as a huge reputable bank how do you use such careless courier services .the documents were first put into international mail taken out and since then just left to sit somewhere almost a month later docs still not arrived and i can understand nedbank has done their job by sending the title deed but now what.me as the client is phoning around trying to track these docs as the delay in receiving the docs will just delay the entire process on my sale of the property. So i know expect nedbank to contact the courier company locate the docs and have them sent to the correct place asap .the whole experience is just been so draining .
