I have not been using my cheque account since August last year due to debt review, however, ABSA now demanding bank fees and threatening me with lawyers when I am already under enormous strain paying my debt. This account can be closed. I pay my loan and car finance with ABSA. Please write these bank fees off and close this account as it's not being used. I transferred funds for my loan and vehicle once in March, no other transactions at all.
