Bad service and attitude from call centre agents

I app**** for a load and it was approved. I was sent an sms stating the load is approved and to phone them on a 021 number which I did. The guy I spoke with said that everything is in order he will attach my statements which was already send two days earlier and then the load will be paid to me by 18:00. Then I had two missed calls from a 087 number and I phoned back. It was Sanlam again, but the person told me he cannot assist cause the profile is logged as someone is working on it, but they will phone me back. This did not happen. I phoned again at 16:28 and the agent I spoke with was extremely rude and I asked her to not be so rude her tone was horrible, but now I understand why some agents are so rude. Apparently they work from home that is why I heard a baby in the back ground when speaking to an agent two days earlier. So some of these agents are at home being irritated by family or friends or someone and then they take their moods out on the clients who phone them. This lady just put the phone down on me because I asked her not to be so rude and also she was asking me questions that had nothing to do with her as well. They always only aske ID, name and surname. I phoned back at 16:31 and the same agent answered. I asked her why she put the phone down in my ear and why she was so rude, I want to speak to management. She said there is no managment there. Did not offer a number for management nothing. I said I know its her because I can clearly that its her voice and she is also rude as if she is irritated.

Why must we deal with people working from home (something we are not told beforehand) that are irritated cause they have distractions at home and get treated like *******?

Everytime I phone I am polite.

I have been struggling to get answers for days now and this is not acceptable at all and then I have to accept being spoke to as if I am *******.
