Why are there no evaluators for Johannesburg, North and why do your evaluators work between 10-11 only?

I would like to know why ABSA Evaluators only work between 10:00 and 11:00 and why are there no dedicated Evaluators for Johannesburg North area. I had to go and open for my sister's property for an Absa Evaluator on Monday, 05 March but had to reschedule to 07 March at 10:30 because, John, the Gardener could not find the keys to open the house. The evaluator was advised of this fact and therefore he did not have to come to the property. On the scheduled date, 07 March I called the evaluator to advise I was running late and advised him that I would be there at 10:45. When I got there I saw him waiting at the gate. I got out of the car, greeted and apologised for being late he never responded nor even bother to introduce himself, I had to confirm if he was the evaluator from Absa. I tried to open the gate with the bunch of keys I had but none would open. I called the John to confirm which key he had used to lock the gate and his response was the gate was left on manual mode. I could see how more irritated the evaluator was, he was trying to push the gate and I told him to stop because it would have already moved if it was on manual mode. At that point he just took pictures of the house and told me that he would tell the bank that he was denied access to the property. For him to lie like that is appauling. I asked him who and how was he denied access when I was there with him. He saw himself that the keys would not open. I find this behaviour very unprofessional and and I am more so finding it shocking that Absa as a brand would have one evaluator to service East and North, unless of course this guy is a preferred service provider by somebody within Absa and if that is the case why should this have such a negative impact to Absa as a brand and its customers, who are based North of Johannesburg, and who are to be dictated by JK Evaluation Services' terms of wanting to work only between 10&11am.

I've found this representative to be unprofessional and in raising his voice trying to cause a scene, I was fortunate to have a security patrol car, of which the guard stopped and enquired what was going on. I am the available person who can grant access to the property during working hours and I would personally not like to see this service provider sent for this evaluation again. Again unless of course he is getting preferential treatment from within Absa.

I feel Absa needs to hear my side of the story on this matter because he is a complete **** that he was denied access to the property.
