Worst, rude, service ever

Am writing regarding this REFERENCE NO:C-***7,After struggling for a long time, eventually after an hour, I spoke to Mbali Ndlovu who promised to work on my query, a day later she sent me an sms to say, my query has been resolved, and that she will call me shortly, she never called until today, so last Friday, I called Absa again spoke to a lady who was rather rude and told me that she will not be able to assist me, that I should speak to Mbali, she also said she send Mbali an email to contact me but, NO ONE CONTACTED ME FROM THAT DEPARTMENT, so what annoys me the most is that each day, I received about 5CALLS FROM The Absa COLLECTION DEPARTMENT, TELLING ME THAT, MY CURRENT ACCOUNT IS STILL NOT FIXED BUT RATHER ON ARRERS, at first they said with R107. 00,now they saying +-350.00... WHAT IS GOING ON Mbali, is this how you treat your customers? Am very upset because I explained everything to you and you promised that, this will be fixed but still... IT IS NOT FIXED, YOUR MESSING UP MY BUREAU STATUS!!!
