Terrible service

Extremely dissatisfied with service. Spoke to Samuel Mkhize who authorised a teller withdrawal on my account via telephonic and email communication, when I arrived at the bank on Thursday 28th March I was told this could not be done because the account is on hold and I at no point was made aware or notified the account is on hold by anyone due to the hold I could not get a temp card to do the withdrawal and the consultant contacted Samuel who advised he will have the hold uplifted in 10 minutes which I then could not wait as I had to return to the office so I told him I will come back on Saturday for the withdrawal, when I arrived at the bank on Saturday the hold was not uplifted and once again no assistance from anyone. The staff tried reaching out to Samuel to no avail. I did email him this morning and he advised he had sent an email I then emailed again around 12:00-13:00 to follow up on feedback and still nothing no response. Samuel has also advised he did not put the hold on the account and yet no one from fnb has contacted me prior to putting my account on hold to notify me of such. Please can someone contact me regarding the above urgently.
