ABSA Bond

I have taken out a bond with a consultant from the branch, Linda, who was amazing throughout the process. The bond was thereafter dealt with by a bond consultant, Thozama, and initially on finalisation of the bond, everything was ok. Then I app**** for an additional amount which was discussed at the beginning of the process. Since then, the lack of communication and service received has been terrible. As the final part of this process for the additional funds, an insurance certificate is required from the body corporate (not sure why this wasn't requested initially on purchase of the property). The body corporate requested for confirmation from the bank before they could issue a certificate. I then asked Thozama to assist and she said that I would need to send the condition of approval to the body corporate. I called Thozama and explained that the condition of approval contained financial details regarding the bond and I wasn't comfortable sharing that to which the response from Thozama was that it is my responsibility to get the certificate and they can't help. Now I'm in a position where I'm forced to share information just to satisfy the bank for their requirement. I don't understand why it's so difficult to draft an email or letter stating that they require the information rather than forcing me, a customer with all my accounts held at the bank, to share confidential information. If this is the level of customer service I can expect then I will be looking for another bank very soon.
