Feedback on Cancelation amount of homeloan

We sign the selling contract in October and after that we struggle to get the amount from Nedbank for the Tranasaction to be completed. The contract was signed in October and because of Nedbank's poor service we are still waiting for that cancellation amount. Our Attorneys put pressure on them from the start. 3 weeks ago NEDBANK in Secunda did do what they was suppose to do but we are waiting now again for the HEad Office for 3 weeks. This is just not acceptable.
