Unfair and unacceptable

Being a client for over 14 years and cannot get greenbacks again. I had greens backs a year or 2 ago, all of a sudden it no longer appeared on my banking app so when I called in and queried I was told that I had 2 profiles linked to my greenbacks account and I need yo go to the bank to sort. I eventually contacted them now, evertlytime I called the call centre I was told that someone will call and assist me, called again yesterday and was told within 24 to 48 hours I will be contacted. I logged on my app today and spoke to an agent Thato Mokone and was told by this agent that my greenbacks account was closed and I cannot apply again as it can only be done once. The thing is initially when I was told I had 2 profiles on my name is never requested that it should be closed, this was done from your side and now when I am requesting for it to loaded on my profile after several attempts to do this, I get told I cant apply again and thats that! Being with this bank for so many years I find this hard to believe. I will definitely be looking at changing my bank!!!!
