incorrect billing and poor administration

We highly dissatisfied about in which our bond account has being handled by absa head office, first our account has being handled by many people, different people will call us and enquire about the account and we find ourselves dealing with many people. They even called the contractor about house status, why are they not calling us no one knows. The other issue the is the status of our account twice they said we are in areas whereas we are not, if you look at our account the payment due is planned for the 1st July 2015 but they have put our account in areas and they send me an sms saying I'm in areas, I mean who on earth send an sms of an account in areas of 17865 instead of calling the customer . We have received a bad service and absa needs to take away the 17865 they said we are in areas with because the next payment due is 1 July 2015. Lastly we have deposited money into our account for the bank to recalculate our monthly statement and this exercise takes forever we haven't received an answer, what kind of service is this?
