FNB Disappointing Service

I app**** for a loan on the 23rd of May. On the 25th of May in the afternoon I received a sms indicating that the Debi mandate had expired, however no communication was made to advise that it needed to be approved. I contacted FNB immediately and was advised that a new debi mandate would be sent to me to approve. This continued till the Friday the 29th of May. Each day I would contact FNB advising that I am not able to see the new debi mandates which I am apparently being sent. Irrespective of logging in to my phone app or via the internet or via an ATM or via phone banking. The 1st of June I received a call from FNB who did checks with me, indicating that all is approved and would be paid out to me within 30 minutes. I further received an sms to request if I accept the payment and amount I immediately responded yes. Further to that, I have been calling every day - no proper feedback. With the exception of one lady who sent me 1 e-mail showing she had requested feedback and 1 lady who called me Friday last week to indicate she has no feedback. I have no answer. Really bad service! Very disappointed!
