Very Bad Customer Service!!!!!!!!!

Good day I contacted Margaret since last week from Absa Life via email and telephonic regards bank charges that was taken from my account for debit orders reversed on internet banking and she did not contact me at all I had to call her and she just said sorry but still not doing anything about my query, I also send an email to Basani and no reply.....I just wonder how people do their work if they don't respond to emails, they also give the bank a very bad name.....I'm forever sorry giving Margaret and Basani on a previous review good feedback they not worth it. Margaret promised that she will get back to me yesterday but didn't I called and her line is engaged. Absa please employ people that a passion for their work and are there because they value Absa as an employer. What happened to client services!!!!!!!!!!!!!!!!! I request a refund and telephone and data expenses as soon as possible, if not I will expose you on all social media networks , don't call me please send me emails I want everything on black and white!!!!!!!
