FNB home loans

I had a bond for 22 years now with FNB and I am in a process of selling the same property. We are the process of registering the property to the new owner and FNB lost my title deeds. The property should have been registered by end of April but this has caused me unnecessarily costs whereby I had to pay m****cipality again for clearance certificate. FNB doesn't even want to pay for the title deed they lost. I sent an email to their complaint desk, no response. When you call the number they provided for complaint it doesn't even go to that department. FNB doesn't care about clients .
