Bad service

In Newcastle Mall on the 15th of July i was depositing funds to a person that needed it for medical reasons, as i was in the process of depositing, i had punched in the account number, my cell phone number, and the reference. As the atm gave me the option to insert the funds, as soon as i did that, all the atm's switched off. What really confused me was that the security suddenly told us that the atm's having been switching off alot that day, my question was that why wouldnt fnb stop people from using them since this was happening. I feel like fnb does not really care about their clients. I reported this to the manger same time, the matter could not be resolved since it was already around 17:30, she told me to come back the next day. When i came back i met another manger by the name of Sbo who just told me i should fill in a claims form and then she will call me, not putting into consideration the urgency of the matter, showing no sympathy whatsoever. I am very disappointed at the service that i got from fnb Newcastle mall. Its really unacceptable. If anything happens to the person i was sending the funds to, i will hold fnb responsible.
