FNB Bad service

I've switched an account from ABSA to FNB account on 02feb2018 and I was told that they will switch all my debit orders smoothly I must not close the account of ABSA immediately. I receive a call around 7 and 8 feb to cornfirm the cell no of my contract with cell c . I followed up on 17th feb noted that they did switched my salary on 17th then I requested previous bank to close the account and I made payment of R 900 to assist with it. On 06 April 2018 was called by legal department of FNB all I can get was they try to shift the blame meaning Fnb try several times to call me regarding cell c no of which I did respond and on other debit orders I did myself but I fail on others as they require a bank to cornfirm guy was not prepared for the call as I was telling the story he had no clue meaning he just picked up the phone and call me without gathering all the information about the matter on hand at that moment he then drop the phone send me email that the matter is in progress unprofessional like that. I did indicate that am expecting this matter to be attended urgently as now is the 3rd month. I am expecting FNB to pay for the unpaid charges of ABSA as it's FNB fault. I did attached all the documents on the previous communication with FNB.
