bad service

I have a loyal and trust worthy client at absa until i got retrenched in april, and credit life the insurance has been paying for my personal loan as i had insured with them. I called this morning to make a payment arrangement as i am still unemployed and dont want my account to be in arrears, and i am told i owe R891.00...tried to understand where the amount is coming from spoke to 3 consultants (Tsietsi, Mbali and Keagan) who couldnt explain, requested to speak to a supervisor after spending over R200 worth of airtime and the calls just kept on being disconnected. Im disgusted by the service and tequire immediate assistance.
