Pathetic service

There was *****ulent activity on my account . I requested the bank to do a reversal , they advised that the ***** team would get back to me within 72hrs , I logged this on 21 Dec and today is 13 Jan . Whenever I call they say they investigating and will get back to me or they have escalated the matter to the manager and I would receive a call the next day . I changed from FNB thinking discovery would be better but they are absolutely pathetic as a bank . They could have done the reversal of funds and continued the investigation but nothing has been done. The lack of communication is a serious concern . When they see this post they would still reply that they apologise and will investigate and get back to me as they jahr done with other complaints . All they do is investigate but no results to show for there investigations.
