Atrocious Behaviour

I made an online claim to absa. Unfortunately the company they chose to use is absolutely rude.

Firstly they showed up at my house unannounced. My son calls me at work to say someone's at the gate. I instructed him to hand over the phone knowing it was probably to do with the claim. The person then orders me very rudely to come home & let them in. All the while I am trying to explain that I am at work & can't just leave. I was under the impression that I would be called in advance to make arrangements so I can avail myself. I certainly was not expecting to have strangers just pitch up at my house & to be spoken to in this manner.

Is this the caliber of people that absa appoints for their clients.

I do not want these people on my property.

To top of their bad behaviour they are sending multiple messages to taunt me. Is this really acceptable behaviour from people that treat your clients in this manner.
