Horrible service at your call Centre and phone dropped on my ear

I have been playing lotto on the absa banking app without any problems.Winnings of R5 have bee transferred without any problems. Now all of a sudden winnings are not transferred as before when when I called the call Centre I was rather rudely talked to by a call Centre agent who dropped the phone on my ear. I'm not sure if this is how absa treats its clients but if that is the case they must just tell us to go and open accounts with other banks who actually know how to treat and talk with their clients and don't have foolish little boys dropping phones on clients ears... I'm hope I get a response soon as I see they have a habit of not even bothering to answer.
