Service at Absa Banks

i have been to Absa Horizon View Roodepoort Gauteng twice this week to close my accounts and on both occasions there is only 1 tell and 6 to 8 people waiting to be help and the tellers take there time. yesterday i went again and when i arrived at the door at 09.05 the young lady at the door just said to me the bank is off line NO good morning or sorry. i then drove to Absa Clearwater and was told they where also off line so i did some shopping and came back and they where online. i waited one and a half hours to see a teller then taken into the bank where there were 2 tellers attending to clients and 4 people sitting in chairs waiting to be attend to so i would have had to wait my turn. after waiting 20 minutes the line still did not move so i walk out very upset as i have had 2 knee operations 8 weeks ago plus i am 76 years old. why do clients had to be treated like this and can see why Absa is loosing clients. thanks Mrs A Buyskes.
