Bad Service

We app**** for and extended loan on our home loan. The initial service was great from application to sighning the contract was less than 2 weeks. When receiving the contract (02/07/2015) we weren't happy with the Nedbank insurance which doubled in price with this extended loan. So we decided to get our own insurance and sent the proof of insurance to the lawyers on the same day (02/07/2015). The lawyers said it would take 1-2 days for the new contract. It has been 12 days since. We have made numerous calls following up on this and no one gets back to us on how long this will take. I also went to see the banker who initially helped us, and she tried to follow up from her side. The whole delay is an amended declaration from the Nedbank insurance division and they even refuse to assist the banker with our query. How can an amendment take almost 2 weeks???? And with no one even keeping the client up to date on what is happening. We have been sent from pillar to post and no one can justify this hold up. BAD SERVICE.
