Terrible service from Absa

I had a bad experience with Absa on Friday evening I bought Telkom landline airtime with my Absa app the airtime didn't go through so I went to the Absa branch Westgate where I was shocked by the kind of services I received. They did not have a backup of the generator when they were load shedding and as soon as the power came back on at 11:00 they said they would not be servicing anyone anymore even though they had an hour to service people that were waiting in line. Then I called Absa to refund my money they kept on saying that they will put in the airtime, but I told them that I want my money back I called three times with my airtime and they said they will call me back after 24 hours I waited for their call and they didn't call me back AND I THEY Never **** notes where I said they should make notes. Today I called again at Absa to refund my money and instead of refunding me they sent the airtime I am ver angry at Absa for the bad service I received.
