Access bond which you cant seem to access

Have had no luck with Nedbank from the start of the home loan application, took them three attempts to get the property title correct which delayed the whole process a few months ,in which i had to pay occupational rent.On accepting Nedbanks offer for the home loan. a access bond was signed for, to this day we have now tried twice to access the funds available in our account with no luck. First time we where told we did not have a access bond and we must apply for a new bond.As i knew what we had signed for, we approached our local branch manager at Northmead square to be told they can't assist us, as the home loans are no longer handled in the branch we must contact the call center.On deciding to rather just leave the whole thing, i was contacted by a sales consultant saying that the loan was approved we must come and sign FOR THE NEW BOND. Then a second sales consultant phoned saying we must rather take a less as we won't have to pay the costs as we have an access bond, which we then left as my wife was on maternity leave at this point .Now trying this time again after receiving an approved letter for the full amount, i get a call saying we can come sign but for half the amount.
