FNB unprofessional financial institution with *********** staff

On Saturday, 7 November 2020 my account was three times debited with R110. I went onto the secure chat of FNB and they advised me that it was for unpaid FNB debit orders. The lady further advised that I must can call the collections department if I dispute the debit orders. I called and spoke to a lady by the name of Thandazile of the loan collections department. She advised me that it is not fees but amounts that were debited for my loan account but were never allocated. She ask me to gave her time until Thursday, 12 November 2020 to do an investigation into my account. Up until today she never contacted me back. I called FNB on Friday 13 November 2020 trying to get hold of Thandazile and hold on for more than 1 hour. The consultants transferred me from pillar to post which is so pathetic and unprofessional. I need someone to come back to me please to rectify my account. i also want proof of fnb internal unpaid debit order fees pricing for premier bank customers. FNB bank is a bank that is not there for its customers but rather wants to ***** from them especially in this trying times of the COVID 19 Pandemic.
